Bonifatius-Kirche, Romanesque church in Großheide, Germany.

Bonifatius Church is a Romanesque church in Großheide with a 42-meter tower that combines architectural elements from the Romanesque and Gothic periods. Inside, visitors can see a 13th-century baptismal font made of Bentheim sandstone, decorated with lion figures at its corners.

A document from between 1106 and 1116, surviving only as a 1930s copy, names the Arle church and assigns it to the Bremen cathedral chapter through provost Werner. The wooden church was demolished in the early 13th century, and the present building rose on a warft raised to 8.50 m above sea level, with a 7.50 m granite foundation. In 1532 soldiers of the Duke of Geldern, encamped at Esens, stripped the church of its lead roof.

The carved altar displays scenes from the Passion of Christ and shows influences from northern artistic traditions of the region. Visitors can observe how these religious images shaped the spiritual life of the community through the centuries.

The church stands on elevated ground and remains accessible as an active place of worship. Visitors should remember this is a functioning religious space where respectful conduct is expected.

The second bell tower, built on four-metre-thick foundations, was meant to serve as a refuge from storms and wars. A twelve-year-old child was buried in its foundations, since people believed this made the tower impregnable. East Frisian chieftains at war destroyed it anyway in September 1430.
