St. Willehadi-Kirche, Romanesque fortified church in Wremen, Germany

St. Willehadi Church is a single-nave Romanesque church built around 1200 on the village mound of Wremen, its walls of Rhineland tuff shipped in by sea; the south wall was later renewed in brick while the north wall remains tuff. The nave is divided by pilasters with a round-arch frieze under the eaves, and the lower rectangular choir has a low chancel arch. The massive west tower, originally from the first quarter of the 13th century, was cut down to roof height in 1914 and rebuilt to 50 m in 1930, so its stone colours differ visibly.

Built around 1200 as a fortified church on the village terp of Wremen, it was raised from precisely cut Rhineland tuff carried by ship; the north wall still shows that stone, while the south wall was later renewed in brick. The west tower dates from the first quarter of the 13th century. In 1914 it was cut down to roof height so it could not guide enemy ships into the Weser, and in 1930 it was rebuilt to 50 m; the differing stone colours remain visible.

The church is dedicated to Willehad, a missionary from Northumbria who preached among the Saxons from 772 and became the first Bishop of Bremen. The wooden baptismal stand, donated in 1738 by Eggerich Eggers, carries a lid with a figure of Christ holding the baptismal command, surrounded by the four Evangelists and a dove. The pews and choir boxes of the 17th and 18th centuries are inscribed with Bible verses and names.

The church stands on the village terp (Wurt) of Wremen, its west tower visible from the surrounding marshland. The north wall preserves the original tuff stone, while the south wall and the rebuilt upper tower show later brick and differing stone colours. The tower was reduced to roof height in 1914 and raised again to 50 m in 1930.

The ship model above the centre aisle is a kuff named "Wremen"; the sources describe it as a 19th-century vessel. It recalls the February 1962 storm surge that struck the parish, and the survival of the village is what the model commemorates.
