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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
