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 Cathedral of Saint Mary Major, often called Lisbon Cathedral or simply the Sé, is a Roman Catholic cathedral located in Lisbon, Portugal. The oldest church in the city, it is the seat of the Patriarchate of Lisbon. The cathedral has survived many earthquakes and has been modified, renovated and restored several times. It is nowadays a mix of different architectural styles.
The site where it stands was the principal mosque of Lisbon when it was an Arab settlement. The construction of the cathedral started around 1150, three years after the city was conquered from the Moors during the Second Crusade. Shortly after the victory the English knight Gilbert of Hastings was named bishop of the city of Lisbon.
One good reason to visit the Cathedral is to visit its charming cloisters located in the back. There are several tombs in the cathedral, the most notable of which is the beautifully sculpted tomb of Lopo Fernandes Pacheco and his wife.
