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.

The Kolín synagogue is the largest synagogue built in the Czech Republic until the 18th century, and outside of Prague it is the oldest and most valuable monument of its kind in the country. It was built on the site of an older wooden house of prayer as early as the turn of the 14th and 15th centuries. The inscription of a date on the memorial stone inserted into the eastern façade is the evidence. –

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.
