Bilstein castle is located on a spur which falls away steeply on three sides so that the castle's defences only needed to be oriented towards the hill to the northeast. The appearance of the castle is thus dominated by its two round towers, each with a diameter of about eight metres: the Chapel Tower in the northwest and the Hohnekamp Tower in the southeast. The towers are connected by a tunnel under the castle courtyard, above ground is a 20th century archway.
The castle was built between 1202-1225. The Electorate of Cologne conquered it after a siege in 1445. Later it has been used for administrative purposes.
The northwestern wing of the main ward and the central block in the southwest are historical structures. By contrast, the wing in the southeast was built in 1978 to expand the hostel. On the valley side of the central block is a portal terrace (Söller) on which a prominent lime tree is growing.
Today a brick bridge spans the moat between the inner and outer baileys. The moat has been partly filled-in and is about 15 metres wide. The outer bailey comprises three buildings, which are referred to as the gatehouse, timber-framed house and festival hall.
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.
