Stadtkirche St. Jakob

The Franciscan Church belonged to the former Franciscan Monastery and is now an Evangelical Lutheran parish church. The monastery was founded in 1281 but ceased to exist in 1548 as a result of the Reformation. The monastery buildings, which had been voluntarily abandoned, first housed a Latin school and then a flat for the widows of the parish priests. After 1805, the buildings were used, among other things, as a salt warehouse. Parts of the complex (cloister, refectory, etc.) were demolished, and much of the inventory was destroyed or sold.

The Synagogue in Hüttenheim is an Ashkenazi synagogue from 1754, restored in 1996. In use until WWII, this Baroque stone building now serves as a dwelling.

St John's Cathedral was built between 1250 and 1274 by the Order of St John as a pillared basilica in early Gothic style. Before that, a chapel dedicated to St Kilian stood on the site. In 1554, the Teutonic Order acquired the entire property of the Knights of St John and carried out reconstruction work. The former flat ceiling of the nave of St. John's Church was replaced by a cross-ribbed vault; the vaults were decorated with the Renaissance painting that is still preserved today. The bell tower was built in several stages. The four lowest floors date from the time of construction. In 1445, the tower was raised by two floors. From 1594 to 1618, the characteristic tower gallery and the hood-shaped tower bulb were built over the octagon.
