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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
