Zarafona Castle is a good sample of late medieval fortification architecture. It is in relatively good condition According to an inscription found on the west external wall, the castle was constructed in the period that the Despotate of Moreas was governed by Theodoros II Paleologos (1407-1448). Therefore it was a construction of the first half of the 15th century, part of the effort of the Byzantines to confront the Ottoman threat.
The castle has an almost trapezoid layout and covers an area of 745 square meters. There are 3 towers, two at the west wind and two at the east. The walls are divided in 5 straight parts of vertical walls.
The central tower is much higher than the other buildings and the walls. It has 3 levels. The ground-floor houses a cistern.
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.
