St. Procopius Basilica is a Romanesque-Gothic Christian church in Třebíč. The history of the basilica is closely associated with the history of the former Benedictine monastery. Before the basilica was constructed there was a chapel of St. Procopius, which was built in the year 1104 and was consecrated by Heřman, Bishop of Prague. Five years later, the monastery already had its own church. This was consecrated in year 1109 by then Bishop of Prague, Jan II. In the crypt of the church Duke Litold Znojemský was buried, one of the founders of the monastery, and three years later his brother and Duke Oldřich Brněnský, the second founder of the monastery, was likewise interred.
The monastery grew rich and its influence swelled. For about half of the 13th century the monastery was rebuilt and fortified. This reconstruction was started in about the year 1240 and finished in the year 1260. The reconstruction meant the disappearance of romanesque architecture in the monastery, but allowed for the new basilica to be built. The basilica is preserved in its original style to this day.
The basilica together with the Jewish Quarter in Třebíč were inscribed as a UNESCO World Heritage Site in 2003.
The basilica was originally dedicated to the Assumption of the Virgin Mary. Saint Procopius became the Patron saint of the basilica on the quincentenary his canonization in 1704. Jan Karel, Count of Valdštejn established a castle chapel of St. Procopius from the presbytery of the basilica.
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.
