St. Viktor Church

The Church of St. Viktor in Guntersblum, Rhineland-Palatinate, is a structure distinguished by its unique “Saracen Towers.” These tower finials, also known as “Crusader Helmets,” are rare in Germany and give the church an unmistakable appearance.
History+
The origins of St. Viktor Church date back to the early 12th century, with construction beginning around 1100. A dendrochronological study of wooden beams from the north tower revealed that the timber used was felled in early summer 1101. A predecessor building likely existed even before this time. The financing of the new three-aisled basilica was shared by the Xanten Collegiate Church (later the Worms Cathedral Chapter) for the choir and nave, and the citizens of Guntersblum for the side aisles and towers. In 1496, the name St. Viktor was first documented. After a demolition of the nave in 1618 and the turmoil of the Thirty Years' War, the new nave was built from 1685 to 1688.
