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.

A unique UNESCO monument – the Cathedral of the Assumption of the Virgin Mary and St. John the Baptist in Sedlec near Kutná Hora is the convent church of the former oldest Cistercian abbey in Bohemia. Together with the Sedlec ossuary, this church forms a wholesome complex of the oldest part of Kutná Hora. The cathedral was built between 1290 and 1320 and combines North French Gothic cathedral architecture with German elements.

The church, which is the dominant feature of Čáslav, dates back to the 12th century. It has undergone six centuries of structural modifications to its present form. In 1910, the remains of Jan Žižka of Trocnov were found in the tower chapel. The observation tower is also a great feature for all visitors.
