Kost Castle is is privately owned by Kinský dal Borgo noble family. It was first proposed by Beneš von Wartenberg in 1349 as a possible construction site and was completed by his son Peter von Wartenberg. It retains most of the original features and is overall very well preserved and maintained.
The castle is known for its so-called 'White tower'. In about 1414 the family of Zajíc von Hasenburg moved there; later the family of Schellenberg (1497 - 1524), Lobkowicz (till 1576) and others; in this time some more buildings were built near the castle and joined to it.
Unlike most other castles in Bohemia, it does not lie on a hill, but on a spit between two brooks. Another peculiarity is the tower, which has a trapezoid-like ground-plan. The trapezoidal tower has the corners facing the areas of most likely catapult attacks. This is to make the missiles glance off the tower walls instead of hitting it headon thereby minimizing the damage.
The castle is open to the public and hosts events and exhibitions.
References:The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
