The Unstrut crossing near St. George’s Church was once an important junction for trade routes. This is the place where the original settlement of Mühlhausen was founded during the Franconian period, named after a mill that once stood there. Following the city’s foundation the 12th century and the building of the city wall in the first half of the 13th century this area became the suburb of Altmühlhausen. While the other medieval suburb churches were first founded in the 14th century, the much longer history of the old Mühlhausen settlement suggests that St. George’s Church, first mentioned in 1356, probably had a predecessor. In comparison to Mühlhausen’s other suburban Gothic churches St. George’s stands out for its unique architecture. The church was built in the 14th century as a double-naved structure with a straight eastern side. The representative façade faces the forking in the road coming from the Unstrut crossing, leading the traffic from the south through the Görmartor towards the lower market (Untermarkt), and from the west to the former royal palace with its castle. Entering the church the structure at first seems somewhat unevenly proportioned – a wide main nave separated by archways from a narrow northern aisle containing the sacristy – but these parts are brought into harmony by the massive eastern side with its dominating tracery windows, moldings, arches, and a high niche. Only a closer examination reveals the truly remarkable architectural achievement behind the design. Along the long sides of the church representative portals are embedded. On the southern side there is a remarkable chapel annexe from the late 14th century. The west tower with the portal was overhauled in the 18th century. The octagonal half-timbered turret was originally based on the design of St. Kilian’s Church and Martini Church before it received today’s modern slated façade. St. George’s Church houses one of the most valuable medieval artefact, a late Gothic retable showing the coronation of the Virgin Mary. Outside, at the south-east and the north-east corners nine flood markings remind us that the nearby river posed a significant threat over the past centuries.
