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.

From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
