Protestant church in Heiligkreuz, Church in Heiligkreuz, Weinheim, Germany

The Evangelische Kirche Heiligkreuz stands in the north of Heiligkreuz at the confluence of the Atzelbach and Apfelbach streams. The church is oriented east, with a nave and a polygonal Gothic choir supported by buttresses. The west extension of the nave and the round-arched side windows date from the 18th century. The tower, built in the 15th century on the south side of the choir, has a four-sided tent roof that transitions into an eight-sided spire.

The church is first documented in 1242 when the area was still called Atzmansweiler. The tower was constructed in the 15th century, while a major expansion of the nave occurred in the late 1700s to accommodate more worshippers in the growing community.

The village took its name from the church: the settlement was called Atzmansweiler until the church's Holy Cross dedication, first recorded in the 1496 Wormser Synodale, passed to the place. The church was a filial of St. John the Baptist in Leutershausen and served seven villages, from Rittenweier to Ursenbach. A low wall around the building marks the old churchyard, moved across the street in 1834.

The church is situated on Odenwaldstraße and is easily visible from the road. Services take place every two weeks, with the interior open to visitors afterwards. The small churchyard provides a peaceful spot to pause and enjoy views of the surrounding hills in the Odenwald region.

The organ, built in 1975 by Ernest Mühleisen, has nine registers and was fitted into a Baroque case made around 1740 by Johann Friedrich Ernst Müller of Heidelberg, which came to Heiligkreuz in 1788 from Ilvesheim Castle. The three bells, cast in 1958 by Bachert of Bad Friedrichshall, sound the notes e, d and h.
