Another, younger fortress used to stand in the location of the current chateau. This fortress was probably founded in the middle of the 15th century, after the previous older fortress, located in the south-western direction from Kácov on the left bank of the Sázava nearby Soušice, became dilapidated. Due to the fact that on the turn of the 14th and 15th century Kácov was divided between several owners, it is possible that there were two fortresses existing next to each other over a certain period of time.
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.
The castle of Konopiště was founded at the end of the 13th century, probably by the bishop Tobias of Benešov. It was built as a Gothic fortress copying the design of French castels.First building alterations were ordered by George of Šternberk at the end of the 15th century, and later by Hodějovští of Hodějov in the 17th century. In the 18th century, Vrtbové of Vrtba converted the castle into a Baroque palace. Francis Ferdinand d’Este, who bought it in 1887, had it rebuilt into a grand emperor’s residence.
The predecessor of the current chateau in Líšno used to be the Castle of Léštno, established probably after 1367 when the sons of Ondřej of Dubá divided their inheritance. Beneš of Dubá who was given this section of land built his seat in a suitable spot protected by swamps and ponds. His son Václav of Dubá accompanied Master Jan Hus to Constance, however he did not join the Hussites and therefore the Taborites besieged his castle in 1420.
The upper Gothic style castle from the 14th century was reconstructed into a Renaissance chateau in the 16th century. František Maxmilián of Talmberk built a chateau in 1675 with the participation of the architect O. de Guarde.
