Týnec nad Sázavou - Zbořený Kostelec
The castle is probably of royal foundation, although the beginnings of its history are not documented. The first written mention of Zbořený Kostelec (originally called Kostelec nad Sázavou) dates back to 1341, when King John of Luxembourg gave it as a pledge to Oldřich of Valdek, the owner of neighbouring Týnec.
