The Palace of the Despots dominates the Upper Town of Mystra. It is a great complex of buildings belonging to different times of construction. They started to be built by the Franks, possibly by Guillaume de Villehardouin, and were completed by the Byzantines (the Despot was usually a son or brother of the Emperor).
These palace constitutes a great example of the Byzantine architecture. The whole building complex is L-shaped and has been well-preserved until our days. The palace has four constructions. Some of them have 4 storeys, while others are two-storey mansions. The first building was the residence of the noblemen and the second one was the throne hall.
The Despot used to live in the fourth building, a four-storey construction dating from 1350-1400. The fifth building, built in the 15th century, was the palace of the Paleologos family. All buildings have numerous arches, chambers, attics and cellars. The exterior area is quite austere.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
