Old church in Wommelshausen, Medieval church in Wommelshausen, Germany.

The Old Church in Wommelshausen is a towerless rectangular hall church of rough greywacke rubble masonry, about 13 by 9.3 metres, with walls 1.2 to 1.3 metres thick. Its steep slate roof carries a slender octagonal ridge turret with a Gothic pointed spire and cross. The south wall has two small high round-arched windows with squat pointed outer arches, and the former Romanesque priest's door, reopened in 1996, now serves as the entrance.

The church is dated to the 10th–11th century, the transition from pre-Romanesque to Romanesque; neither patron nor exact construction date is known. Dendrochronology documents repairs to the south wall crown and both gable walls in 1269, 1274 and 1284, and an L-shaped west and south gallery built in 1485–1487. After damage from looting and warfare in the Thirty Years' War, gables, masonry, roof and roof turret were repaired between 1652 and 1660. The choir was demolished in 1720, the same year a major renovation began, completed in 1726.

The church is also called the Wommelshausen chapel. Its L-shaped west and south galleries, installed between 1485 and 1487, are the earliest documented galleries in the surrounding region. The former priest's door in the south wall, walled up for centuries, was reopened in 1996 and now serves as the entrance.

The former priest's door in the south wall, walled up for centuries, was reopened in 1996 and now serves as the entrance. The main portal on the north side sits below a rectangular window enlarged in 1922. The walls are about 1.2 to 1.3 m thick, and the two small windows high in the south wall are the originals.

The east wall does not meet the building axis at a right angle but is bent southward at 93 degrees, creating an axis kink of about 3 degrees toward the demolished choir. The church axis was aligned to the sunrise of its founding day, at an orientation of 113 degrees from north.
