Gamburg Castle was built in the mid-12th century by arcbishops of Mainz. Unlike many other castles, Gamburg was indeed renovated several times, such as during the Renaissance, but it was never destroyed and was continuously inhabited. Even during the Peasants' War, it remained intact thanks to the personal intervention of Götz von Berlichingen, making it one of the few castles to do so.
At the center of the castle complex with an almost oval layout stands the Romanesque keep. Surrounding the inner courtyard are the former stables, the so-called Forester's House, and the opposite 'castle,' consisting of the chapel tower, the great hall (Palas), the Middle Building, and the Rear Building, which has housed a chapel since 1921. The inner castle was surrounded by a fortification with six semicircular shell towers, a round corner tower, an outer gate with two round towers, and the moat later transformed into a baroque castle park.
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.
