The Pantanassa Monastery is a monastery in Mystras. It was founded by a chief minister of the late Byzantine Despotate of the Morea, John Frankopoulos, and was dedicated in September 1428. It is the only monastery on the site still permanently inhabited. Today it is inhabited by nuns providing hospitality. Its beautifully ornate stone-carved façade is of architectural note.
Pantanassa Monastery is part of the UNESCO World Heritage Site of Mystras.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
