The Church of Agioi Theodoroi is one of the oldest and largest chapel in Mystras. It is located in Kato Hora, the lowest part of Mystras Old Town. The church was constructed between 1290-1295 by the monks Daniel and Pahomios. Originally, it was the katholikon of a monastery and then it became a cemetery church.
The architecture of the church is different than the usual Byzantine architecture and ressembles to the Monastery of Osios Loukas in Distomo Boetia, but in a more developed form. The architecture gradually points to the top and the dome is pretty impressive. The interior of the church distinguishes for the impressive frescoes that date from the 13th century, such as the portraits of the Emperor Manuel Paleologos. In this church, there is also the tomb of the Despot of Peloponnese Theodore I.References:
The eight towns in south-eastern Sicily, including Ragusa, were all rebuilt after 1693 on or beside towns existing at the time of the earthquake which took place in that year. They represent a considerable collective undertaking, successfully carried out at a high level of architectural and artistic achievement. Keeping within the late Baroque style of the day, they also depict distinctive innovations in town planning and urban building. Together with seven other cities in the Val di Noto, it is part of a UNESCO World Heritage Site.
In 1693 Ragusa was devastated by a huge earthquake, which killed some 5,000 inhabitants. Following this catastrophe the city was largely rebuilt, and many Baroque buildings from this time remain in the city. Most of the population moved to a new settlement in the former district of Patro, calling this new municipality 'Ragusa Superiore' (Upper Ragusa) and the ancient city 'Ragusa Inferiore' (Lower Ragusa). The two cities remained separated until 1926, when they were fused together to become a provincial capital in 1927.
