The Decanal Church of St. Bartholomew is both the dominant of Kolín as well as the most valuable monument of this historic town. The early Gothic church was founded in the middle of the 13th century and its construction was carried out in several stages by orders of King Přemysl Otakar II and his successors, the last construction works were done at the beginning of 14th century.

The whole area of the so-called Cathedral Hill, which was revitalized extensively in 2018–2020, is truly unique. You will find here most notably the ossuary with rich ornamental decoration or the building of the former parish school, which houses an interactive exposition. The bell tower is a place where the cathedral treasure is kept and a lapidarium can be found. From atop it also offers a view of the town centre. The green baileys invite you to have a walk and relax in the herb garden or in the rosarium.

The modern Jewish community in Čáslav began its history in the mid-19th century. At the end of the century, the Jewish inhabitants of Čáslav experienced a period of social and cultural flourishing, which culminated at the turn of the century with the construction of a new synagogue on the former Rudolfova třída (today’s Masaryk Street No. 111).

The municipality approached the prominent Viennese architect Wilhelm Stiassni, who had also participated in the construction of the Jubilee Synagogue in Prague on Jerusalem Street. He designed a synagogue in the Moorish style for Čáslav, which was to replace an older house of prayer documented from the mid-19th century. The plans of this Jewish builder were promptly approved by the Israelite Association and the municipal authority in 1897, but it took two more years before construction began. The possible cause was lack of finance. Not only the inhabitants of Čáslav and its surroundings, but also the Rotschild family in Vienna contributed to the construction. Construction work began on 13. March 1899 and already on 2.9.1899 the ceremonial approval took place.

The Čáslav synagogue is a building of high architectural quality and is protected as a cultural monument of the Czech Republic.

It was Giovanni Domenico Orsi, an important builder of Jesuit buildings and an Italian architect born in Vienna, who was the author of the project of the early Baroque building. The partially preserved plans show that he originally chose an E-shaped plan and the current F-shaped plan is the result of the project never being fully completed. After Orsi’s death, Carlo Lurago continued the construction and the College was completed in 1750.
