Neuravensburg Castle was built at the end of the 12th century by the Counts of Argengau, mentioned in 1271, and destroyed in the Peasants' War of 1525. From 1614 to 1617, the castle was reconstructed and expanded into a castle by Abbot Bernhard Müller of the St. Gallen Abbey. In 1836, the castle was sold for demolition, and from 1837 to 1845, it was partially dismantled.
In 1992, the city of Wangen purchased the castle ruins and carried out further restoration work from 1995 to 1996. Besides the keep ruins with a viewing platform, which is accessible from the inside, the foundation walls of the palace are still preserved. The entrance to the castle ruins is located at Hagmühleweg. Following its establishment in 1987, the Neuravensburg Castle and Homeland Association took over the responsibility for the preservation and research of the castle complex.
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.
