The Baroque chateau dating back to 1739 is currently used for private purposes. There is a birthroom of the poet Svatopluk Čech inside with an exhibition on his life and work.
Počátkem 18. století byla původní tvrz přestavěna na barokní zámek. Zámek je v současnosti pro veřejnost nepřístupný a nachází se zde léčebna pro osoby postižené Alzheimerovou chorobou.
In the north-western direction from the current Komorní Hrádek there used to be the smaller castle of Hrádek Čajchanov, located on a promontory steeply falling into the Sázava valley and founded probably towards the end of the 13th century. Its scarce remnants have been preserved in a location approximately 200 metres from the castle. In about 1400 it belonged to Jan Zoule of Ostředek who, together with his cavalcade, took part in a minor skirmish in Bohemia at the time when King Václav I. was captured by the Noblemen’s Union. In 1404 Zoule’s cavalcade was captured by the land protection army and Hrádek was conquered and reduced to rubble. The estate, where the small chateau used to stand, was given as a gift of the King to Vice-Chamberlain Mikuláš.
