The historic town centre is well preserved and is protected by law as an urban monument zone.

The history of Čáslav begins in the 9th century with the founding of a gord and settlement called Hrádek.

A new royal town with a huge square was founded by King Ottokar II of Bohemia next to Hrádek in around 1250.

[9] The town's football club, FK Čáslav, plays in the lower amateur tiers.

[11] The Church of Saints Peter and Paul is an early Gothic building from the end of the 13th century.

The building included the Romanesque Church of St. Michael from the 11th century (today's sacristy), which originally stood here.

A unique monument of the Čáslav Gothic fortifications is the cylindrical Otakar's Tower, which stood at the Brod Gate.

[5] In 1910, part of the skull of the Hussite general Jan Žižka was discovered in Čáslav parish church.
