Reform movements in the late 14th and early 15th centuries in Bohemia and Moravia were associated with the work of Jan Hus, a university professor and theologian who was influenced by the ideas of the English reformer John Wycliffe
Bethlehem Chapel (Betlémská kaple) was built in the 1950s on the site of the original 14th-century chapel, which became famous as the pulpit where Master Jan Hus preached and was designated as a place for sermons in the Czech language. Everything that was preserved from the original chapel was put into the new building, designed by the architect Jaroslav Fragner. Valuable vestiges of the chapel‘s original decoration are fragments of treatises by Jan Hus. The contemporary frescoes copying illuminations from the Jena Codex harkens back to the original atmosphere.
