Franziskanerkirche

The parish church of St. James was started from the east in 1311. The eastern choir was completed in 1322, but the work stopped. The stained glass windows in the choir were made between 1350 and 1400. Construction was resumed in 1373 when the body of the naves was erected and completed in 1436. In the 15th century, the two towers on the side of the choir were also raised. Between 1453 and 1471, the western choir, which was to become the Chapel of the Holy Blood, was built. The church was consecrated in 1485 and in 1522 it was designated for Protestant worship.

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.
