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 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.
