The ruins of a medieval stronghold called Starý Zámek are situated northwest of Tábor in the direction of Sedlec. Its history reaches back to the 14th century.

In 1434 the castle was unsuccessfully besieged by Prokop Holý´s troops; in the early 17th century the castle was plundered by the imperial army and never repaired afterwards. In the early 19th century stone from the ruins was used for construction in the nearby village. Parts of towers have remained from the castle and some walls of the new palace and the gate. Due to its favourable location in forested countryside above two ponds this is a widely sought after location.
