Pátek Castle was originally a summer palace built between 1544 and 1557 by John the Younger of Lobkowitz, one of the richest noblemen in the Czech Kingdom. It is one of the first purely Renaissance buildings in Bohemia. Towards the end of the 17th century it was rebuilt in Baroque style and surrounded by a farmyard.

Valeč Castle is an important Baroque monument with a preserved urban and landscape context. The grounds include the castle, the Holy Trinity Church, a park and a lapidarium with a valuable set of sculptures by Matthias Bernard Braun. The complex shows a complex development from the glory of the noble residence, through fire to restoration.
