The Baroque-style manor house, dominating the village, was built on the place of the former fortress of Ones Tluksa of Lhotice erected in the 14th century. The manor house belonged to Jan and Jiri Ruzek in the 16th century, after whom the manor received its name. The building comprises two wings, with the main two-storey part being almost perfectly square, and the smaller single-storey rectangular wing having an arcade in the courtyard. A farm building on the southern side supplements the whole compound.
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.
Týnec nad Sázavou has a very long history. Its name itself indicates that at the place where the Týnec Castle is located these days – on a high cliff above the river – there was a fortified settlement in the ancient times, the so-called Týnec (“enclosure” or “fortification” was “Týn” or “Týnec” in old Czech). There is a probable connection between the settlement and an old trade route leading from southern Bohemia through the town of Sázava and along the Kostelec Castle to Prague.
