First mentioned in 1349, but possibly older, Buben castle was home of the knights of Buben (means literally 'drum'), and held it´s name even under other owners. The family sold their first castle around 1378 (they had other castles then), but they use the family name Buben until today. The castle often changed owners together with the surrounding lands, it wasn´t used for living because of it´s isolated position in the 16th Century, and began to deteriorate but only slowly, because there was nobody around to disassemble the stone for their own use. It was a partial ruin in 1912, when first larger repairs were made by the Czech tourist club. A through conservation was done in the 1930ies, but a very unprofessional repair was done in 2010 with modern materials, which destabilized the repaired parts and a bastion completely collapsed in 2013. because the used concrete sucked in too much water and became too heavy for the old wall. The future for now is unsure.
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.
