This church, begun in 1365, dominates Old Town Square, and boasts magnificent steeples in the Gothic style. From the early 15th century until 1620, Tyn was the primary Hussite church in Prague. George of Poděbrady, the Hussite king, took Utraquist communion in this church and used a gold chalice. The form of a chalice, the Utraquist symbol, was then mounted on the facade. After 1621, the chalice was melted down to help form the Madonna statue that replaced it. The entrance portal on the north side of the church is beautifully decorated with scenes from Christ's passion. Notable interior features include a 15th century Gothic pulpit and a pewter font built in 1414. Behind the church is the Tyn courtyard done in various architectural styles.
