Sebastianskapelle, Historic chapel in Ladenburg, Germany.

The Sebastianskapelle stands as a medieval stone chapel featuring Gothic and Baroque architectural elements, with elaborate trompe-l'œil paintings depicting saints and apostles adorning its interior walls.

Originally built as a court chapel for the bishops of Worms, the Sebastianskapelle dates back to at least 1266 with some Carolingian-era structural elements, serving various religious denominations throughout centuries.

The chapel holds the epitaph of three Cronberg children who died in their birth year, and the tomb slab of Stephan Alexander Würdtwein, the last auxiliary bishop of Worms. The high altar and two side altars date from 1737, when the chapel was re-consecrated by auxiliary bishop von Merle on 5 May.

Currently closed to the public due to ongoing restoration work addressing structural damage, the chapel requires comprehensive renovation efforts to preserve its historical integrity for future generations.

The organ was built in 1790 by Heidelberg court organ builder Andreas Krämer for St. Gallus Church and only moved into the Sebastianskapelle in 1865 by Carl Göller. Organ builder Vleugels restored it in 1982; it has 18 stops on two manuals and pedal. In February 2018 the Catholic parish sold it for €15,000 to the Heidelberg Christusgemeinde and it was dismantled.
