Originally
 built by King Songtsen Gampo in the seventh century, Potala Palace is 
located on the Red Hill of Lhasa, Tibet. Destroyed by lightning and war,
 Potala Palace had been rebuilt by the Fifth Dalai Lama in 1645. Since 
then, Potala Palace has become the seat of Dalai Lamas and also the 
political center of Tibet. The thirteenth Dalai Lama extended it to the 
present size, 117 meters (384 ft) in height and 360 meters (1,180 ft) in
 width, covering an area of more than 130, 000 sq meters (about 32 
acres). Mainly comprised by the White Palace (administerial building) 
and the Red Palace (religious building), Potala Palace is famous for its
 grand buildings, complicated constructions, devotional atmosphere and 
splendid artworks.
Perched upon Marpo Ri hill, 130 
meters above the Lhasa valley, the Potala Palace rises a further 170 
meters and is the greatest monumental structure in all of Tibet. Early 
legends concerning the rocky hill tell of a sacred cave, considered to 
be the dwelling place of the Bodhisattva Chenresi (Avilokiteshvara), 
that was used as a meditation retreat by Emperor Songtsen Gampo in the 
seventh century AD. In 637 Songtsen Gampo built a palace on the hill. 
This structure stood until the seventeenth century, when it was 
incorporated into the foundations of the greater buildings still 
standing today. Construction of the present palace began in 1645 during 
the reign of the fifth Dalai Lama and by 1648 the Potrang Karpo, or 
White Palace, was completed. The Potrang Marpo, or Red Palace, was added
 between 1690 and 1694; its construction required the labors of more 
than 7000 workers and 1500 artists and craftsman. In 1922 the 13th Dalai
 Lama renovated many chapels and assembly halls in the White Palace and 
added two stories to the Red Palace. The Potala Palace was only slightly
 damaged during the Tibetan uprising against the invading Chinese in 
1959. Unlike most other Tibetan religious structures, it was not sacked 
by the Red Guards during the 1960s and 1970s, apparently through the 
personal intervention of Chou En Lai. As a result, all the chapels and 
their artifacts are very well preserved.
2. Mont Saint-Michel: a Medieval Castle on a Small Island
Le
 Mont-Saint-Michel (English: Saint Michael's Mount) is a rocky tidal 
island and a commune in Normandy, France. It is located approximately 
one kilometre off the country's north coast, at the mouth of the 
Couesnon River near Avranches. The population of the island is 41.
Formation
In
 prehistoric times the bay was land. As sea levels rose erosion shaped 
the coastal landscape over millions of years. Several blocks of granite 
or granulite emerged in the bay, having resisted the wear and tear of 
the ocean better than the surrounding rocks. These included Lillemer, 
the Mont-Dol, Tombelaine and Mont Tombe, later called Mont-Saint-Michel.
Tidal island

Mont-Saint-Michel was previously
 connected to the mainland via a thin natural land bridge, which before 
modernization was covered at high tide and revealed at low tide. This 
has been compromised by several developments. Over the centuries, the 
coastal flats have been polderised to create pasture. Thus the distance 
between the shore and the south coast of Mont-Saint-Michel has 
decreased. The Couesnon River has been canalised, reducing the flow of 
water and thereby encouraging a silting-up of the bay. In 1879, the land
 bridge was fortified into a true causeway. This prevented the tide from
 scouring the silt round the mount.
At low tide surrounded by mud flats - seen from the air
On 16 June 2006, the French 
prime minister and regional authorities announced a €164 million project
 (Projet Mont-Saint-Michel) to build a hydraulic dam using the waters of
 the river Couesnon and of tides that will help remove the accumulated 
silt deposited by the uprising tides, and to make Mont-Saint-Michel an 
island again. It is expected to be completed by 2012.
The construction of the dam is 
now complete (it was inaugurated in 2009), but the project also includes
 the destruction of the causeway that was built on top of the small land
 bridge and enlarged, to join the island to the continent, but also used
 as a parking for visitors. It will be replaced by an elevated light 
bridge, under which the waters will flow more freely, and that will 
improve the efficiency of the now operational dam, and the construction 
of another parking on the continent. Visitors will have to use small 
shuttles to cross the future bridge which will be still open to walking 
people and unmotorized cycles.
3 Predjamski Castle: Integrated in a Cave
llama
 Castle' (Slovene: Predjamski grad or Grad Predjama, German: Höhlenburg 
Lueg, Italian: Castel Lueghi) is a Renaissance castle built within a 
cave mouth in southwestern Slovenia. It is located approximately 11 
kilometres from Postojna.
History of the castle
The
 castle was first mentioned in the year 1274 with the German name Luegg,
 when the Patriarch of Aquileia built the castle in Gothic style. The 
castle was built under a natural rocky arch high in the stone wall to 
make access to it difficult. It was later acquired and expanded by the 
Luegg noble family, also known as the Knights of Adelsberg (the German 
name of Postojna).
The legend of Erazem of Predjama
The
 castle became known as the seat of Knight Erazem Lueger (or Luegger), 
owner of the castle in 15th century, and a renowned robber baron. He was
 the son of the Imperial Governor of Trieste, Nikolaj Lueger. According 
to legend, Erazem came into conflict with the Habsburg establishment, 
when he killed the commander of the Imperial army Marshall Pappencheim, 
who had offended the honour of Erazem's deceased friend, Andrej 
Baumkircher of Vipava. Fleeing from the revenge of the Holy Roman 
Emperor Frederick III, Erazem settled in the family fortress of 
Predjama. He allied himself with the Hungarian king Matthias Corvinus, 
and started to attack Habsburg estates and towns in Carniola, turning 
into some kind of local Robin Hood.
The Imperial forces sent the 
Governor of Trieste, Andrej Ravbar, to siege the castle. After a long 
siege, Erazem was betrayed by one of his men and killed. 
4. Neuschwanstein Castle: the Classic Fairytale's Castle
Neuschwanstein
 Castle (German: Schloss Neuschwanstein, lit. New Swan Stone palace, 
pronounced [n??'?va?n?ta??n]) is a 19th-century Bavarian palace on a 
rugged hill near Hohenschwangau and Füssen in southwest Bavaria, 
Germany. The palace was commissioned by Ludwig II of Bavaria as a 
retreat and as an homage to Richard Wagner, the King's inspiring muse. 
Although public photography of the interior is not permitted, it is the 
most photographed building in Germany and is one of the country's most 
popular tourist destinations. Ludwig himself named it Neue 
Hohenschwangau; the name Neuschwanstein was coined after his death.
The reclusive Ludwig did not 
allow visitors to his castles, which he intended as personal refuges, 
but after his death in 1886 the castle was opened to the public (in part
 due to the need to pay off the debts Ludwig incurred financing its 
construction).[citation needed] Since that time over 50 million people 
have visited the Neuschwanstein Castle. About 1.3 million people visit 
annually, with up to 6,000 per day in the summer. The palace has 
appeared in several movies, and was the inspiration for Sleeping Beauty 
Castle (1955) at both Disneyland Park and Hong Kong Disneyland.
In 1923 Crown Prince Rupprecht 
gave the palace to the state of Bavaria, unlike nearby Hohenschwangau 
Castle which was transferred to the private Wittelsbach Trust 
(Wittelsbacher Ausgleichfonds), which is administered on behalf of the 
head of the house of Wittelsbach, currently Franz, Duke of Bavaria. The 
Free State of Bavaria has spent more than €14.5 million on 
Neuschwanstein's maintenance, renovation and visitor services since 
1990.
5 Matsumoto Castle: Japan's most fascinating castle
Matsumoto
 Castle is one of Japan's finest historic castles. It is located in the 
city of Matsumoto, in Nagano Prefecture and is within easy reach of 
Tokyo by road or rail. The keep (tenshukaku), which was completed in the
 late 16th century, maintains its original wooden interiors and external
 stonework. It is listed as a National Treasure of Japan.
Matsumoto Castle is a flatland 
castle (hirajiro) because it is not built on a hilltop or amid rivers, 
but on a plain. Its complete defences would have included an extensive 
system of inter-connecting walls, moats and gatehouses. In 1872, 
following the Meiji Restoration, the site, like many former daimyos' 
castles, was sold at auction for redevelopment. However, when news broke
 that the keep was going to be demolished, an influential figure from 
Matsumoto, Ichikawa Ryozo, along with residents from Matsumoto started a
 campaign to save the building. Their efforts were rewarded when the 
tower was acquired by the city government. In the late Meiji period the 
keep started to lean to one side due to neglect coupled with a 
structural defect. ( But rumour said that it was because of the curse 
Tada Kasuke had put on more than two hundred years before with his last 
breath on the execution pole.) A local high school principal, Kobayashi 
Unari, decided to renovate the castle and appealed for funds. The castle
 underwent "the great Meiji renovation"(1903-1913) thanks to Kobayashi 
and others. Half a century later, it underwent another renovation "the 
great Showa renovation"(1950-1955). In 1990, the Kuromon-Ninomon (second
 gate of the Black Gate) and sodebei (side wall) were reconstructed. The
 square drum gate was reconstructed in 1999. There is a plan for 
restoring the soto-bori(outer moat) which was reclaimed for a 
residential zone. 
6. Hunyad Castle: were Dracula was held prisoner
The
 Hunyad Castle (Romanian: Castelul Huniazilor or Castelul Corvinestilor,
 Hungarian: Vajdahunyad vára) is a castle in Transylvanian Hunedoara, 
present-day Romania. Until 1541 it was part of the Kingdom of Hungary, 
and after the Principality of Transylvania.
It is believed to be the place 
where Vlad III of Wallachia (commonly known as Vlad the Impaler) was 
held prisoner for 7 years after he was deposed in 1462.
The castle is a relic of the 
Hunyadi dynasty. In the 14th century, the castle was given to John 
Hunyadi Serb, or Sorb by Sigismund king of Hungary as severance. The 
castle was restored between 1446 and 1453 by his grandson John Hunyadi. 
It was built mainly in Gothic style, but has Renaissance architectural 
elements. It features tall and strong defense towers, an interior yard 
and a drawbridge. Built over the site of an older fortification and on a
 rock above the small river Zlasti, the castle is a large and imposing 
building with tall and diversely colored roofs, towers and myriad 
windows and balconies adorned with stone carvings.
As one of the most important 
properties of John Hunyadi, the castle was transformed during his reign.
 It became a sumptuous home, not only a strategically enforced point. 
With the passing of the years, the masters of the castle had modified 
its look, adding towers, halls and guest rooms. The gallery and the keep
 - the last defense tower (called "Ne boisa" = Do not be afraid), which 
remained unchanged from Iancu de Hunedoara's time, and the Capistrano 
Tower (named after the Franciscan monk from the castle court) are some 
of the most significant parts of the construction. Other significant 
parts of the building are the Knights' Hall (a great reception hall), 
the Club Tower, the White bastion, which served as a food storage room, 
and the Diet Hall, on whose walls medallions are painted (among them 
there are the portraits of Matei Basarab, ruler from Wallachia, and 
Vasile Lupu, ruler of Moldavia). In the wing of the castle called the 
Mantle, a painting can be seen which portrays the legend of the raven 
from which the name of the descendants of John Hunyadi, Corvinus came.
In the castle yard, near the 
chapel built also during Vlad The Third's ruling, is a well 30 meters 
deep. The legend says that this fountain was dug by twelve Turkish 
prisoners to whom liberty was promised if they reached water. After 15 
years they completed the well, but their captors did not keep their 
promise. It is said that the inscription on a wall of the well means 
"you have water, but not soul". Specialists, however, have translated 
the inscription as "he who wrote this inscription is Hasan, who lives as
 slave of the giaours, in the fortress near the church".
In February 2007, Hunyad Castle 
played host to the British paranormal television program Most Haunted 
Live! for a three-night live investigation into the spirits reported to 
be haunting the castle.
7. Malbork Castle: World's Largest Brick Gothic Castle
The
 Castle in Malbork (German: Die Marienburg, Polish: Zamek w Malborku) 
was built in Prussia by the Teutonic Order as an Ordensburg. The Order 
named it Marienburg, literally "Mary's Castle". The town which grew 
around it was also named Marienburg, but since 1945 it is again, after 
173 years, part of Poland and known as Malbork.
The castle is a classic example 
of a medieval fortress, and is the world’s largest brick gothic castle. 
UNESCO listed the castle and its museum as World Heritage Sites in 
December 1997 as Castle of the Teutonic Order in Malbork. It is one of 
two World Heritage Sites in the region with origins in the Teutonic 
Order. The other is the Medieval Town of Torun, founded in 1231 as the 
site of the castle Thorn (Torun).
The
 castle was founded in 1274 by the Teutonic Order during their 
government of Prussia and is located on the Southeastern bank of the 
river Nogat. It was named Marienburg after the Virgin Mary, patron saint
 of the Order.
The Order had been based in 
Acre, but when this last stronghold of the Crusades fell, the Order had 
to move its headquarters to Venice. In 1309, in the wake of both the 
papal persecution of the Knights Templar as well as the Teutonic 
takeover of Danzig, the Order under Siegfried von Feuchtwangen moved its
 headquarters into the Prussian part of their monastic state. They chose
 the Marienburg, conveniently located on the Nogat, in the Vistula 
Delta, which allows access by ship.
The castle was expanded several 
time to host the growing number of Knights, and became the largest 
fortified Gothic building in Europe, featuring several sections and 
walls. It consists of three separate sections - the High, Middle and 
Lower Castles, separated by multiple dry moats and towers. The castle 
once housed approximately 3,000 "brothers in arms", and the outermost 
castle walls enclose 52 acres (210,000 m²), four times larger than the 
enclosed space of Windsor Castle.
The favourable position of the 
castle on the river Nogat and its relatively flat surrounding allowed 
for easy access by barges and trading ships, from the Vistula and the 
Baltic Sea. During their governance, the Teutonic Knights collected 
river tolls on passing ships, as did other castles along the rivers, 
imposing a monopoly on the trade of amber. When the city became a member
 of the Hanseatic League, many Hanseatic meetings were held at 
Marienburg castle.
8. Palacio da Pena: Oldest Palace inspired by European Romanticism
The
 Pena National Palace (Portuguese: Palácio Nacional da Pena) is the 
oldest palace inspired by European Romanticism. It is located in the 
civil parish of São Pedro de Penaferrim, municipality of Sintra, 
Portugal. The palace stands on the top of a hill above the town of 
Sintra, and on a clear day it can be easily seen from Lisbon and much of
 its metropolitan area. It is a national monument and constitutes one of
 the major expressions of 19th century Romanticism in the world. The 
palace is a UNESCO World Heritage Site and one of the Seven Wonders of 
Portugal. It is also used for state occasions by the President of the 
Portuguese Republic and other government officials. 
9. Lowenburg Castle: The Disneyland of the 18th century
Within
 the Wilhelmshöhe Hill Park which sits on one end of the city of Kassel,
 there stands what appears to be a medieval castle. However, the 
Löwenburg or “Lion’s Castle” was ordered to be built by the Landgrave 
Wilhelm IX from Hessen Kassel (1743 -1821) (later he gained the higher 
title of Elector Wilhelm I - Kurfürst Wilhelm I), the Walt Disney of his
 era, over a period of eight years between 1793 and 1801 as a romantic 
ruin. It was carfelully designed by his royal court building inspector 
Heinrich Christoph Jussow (1754 – 1825) who had been trained as an 
architect and construction project manager in France, Italy, and 
England, and who had gone to England specifically to study romantic 
English ruins and draw up a plan for the Landgrave’s garden folly. Today
 scholars regard Löwenburg Castle ruins as one of the most significant 
buildings of its genre, in addition to being one of the first major 
neo-Gothic buildings in Germany.
What the Landgrave did here was 
the eighteenth century equivalent of Disney World Tokyo. It is a central
 element of the Wilhlemshöhe castle park which, starting in 1785, the 
Landgrave transformed into a landscaped garden modeled on the English 
pattern, and filled with themed areas – fake Roman aquaducts, fake 
English Castle Ruins, fake Grecian temples, and even a fake Chinese 
Village. In terms of sheer monumental size, however, the fake monumental
 castle ruin of the Löwenburg stands apart from the numerous antiquated 
and pseudo-medieval constructions that served as decorative motifs for 
landscaped parks in other parts of Europe. 
10. Prague Castle: World's Largest Ancient Castle
Prague
 Castle (Czech: Pražský hrad) is a castle in Prague where the Czech 
kings, Holy Roman Emperors and presidents of Czechoslovakia and the 
Czech Republic have had their offices. The Czech Crown Jewels are kept 
here. Prague Castle is one of the biggest castles in the world 
(according to Guinness Book of Records the biggest ancient castle [1]) 
at about 570 meters in length and an average of about 130 meters wide.
History
The
 history of the castle stretches back to the 9th century (870). The 
first walled building was the church of Our Lady[2]. The Basilica of 
Saint George and the Basilica of St. Vitus were founded in the first 
half of the 10th century. The first convent in Bohemia was founded in 
the castle, next to the church of St. George. A Romanesque palace was 
erected here during the 12th century. In the 14th century, under the 
reign of Charles IV the royal palace was rebuilt in Gothic style and the
 castle fortifications were strengthened. In place of rotunda and 
basilica of St. Vitus began building of a vast Gothic church, that have 
been completed almost six centuries later. During the Hussite Wars and 
the following decades the Castle was not inhabited. In 1485, King 
Ladislaus II Jagello began to rebuild the castle. The massive Vladislav 
Hall (built by Benedikt Rejt) was added to the Royal Palace. There were 
also built new defence towers on the northern side of the castle. A 
large fire in 1541 destroyed large parts of the castle. Under the 
Habsburgs some new buildings in renaissance style appeared here. 
Ferdinand I built Belvedere, summer palace for his wife Anne. Rudolph II
 used Prague Castle as his main residence. He founded the northern wing 
of the palace, with the Spanish Hall, where his precious artistic 
collections were exhibited. The Second Prague defenestration in 1618 
began the Bohemian Revolt. During the subsequent wars the Castle was 
damaged and dilapidated. Many works from the collection of Rudolph II 
were looted by Swedes in 1648, in the course of the Thirty Years' War. 
The last major rebuilding of the castle was carried out by Queen Maria 
Theresa in the second half of the 18th century. Ferdinand V, after 
abdication in 1848, chose Prague Castle as his home.
