Marienkirche (St. Mary's Church) is unmissable because of a stubby tower called as 'Fat Mary'. The exact year of the construction is unkown. It is assumed that the building was begun after 1260. In 1275, the building plans were changed and the building continued as a three-nave hall church without a choir. In 1280 the building was mainly completed, but it can be assumed that the construction was still continued until the first half of the 14th century.
A Renaissance pulpit is a rare piece in an otherwise bare church.
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.
