Zwölf-Apostel-Kirche, Frankenthal, Protestant church in central Frankenthal, Germany

The Zwölf-Apostel-Kirche is a Neoclassical Protestant church in central Frankenthal, built 1820–1823 to plans by Johann Philipp Mattlener. Its pale facade has a six-column portico under a triangular pediment, and a tall tower with clock faces, an arched belfry and a green cap stands to the left. Inside the rectangular hall, twelve oval columns carry the ceiling, galleries, pulpit and organ.

Architect Johann Philipp Mattlener designed the church in the early 1820s as a new religious center for the growing town. Intensive bombing during World War II destroyed much of the interior, requiring extensive reconstruction afterward.

The twelve interior columns reference the apostles and shape the space with a clear, ordered arrangement that visitors notice immediately upon entering. This design choice reflects how the Protestant faith was expressed through architecture in this region.

The church is easily reached on foot from the town center and the interior is accessible when doors are open. Contact the parish office in advance if you want a guided tour or need specific information about access times.

The tower is the tallest church tower in Frankenthal. When Johann Philipp Mattlener built the church in 1820–1823, he integrated the historic tower of the Erkenbert ruin into the new tower; the burnt-out spire was altered during postwar rebuilding. Five bells hang in the tower.
