Courtyard synagogue of Detmold, Historical synagogue in Detmold, Germany

The Hofsynagoge is a two-storey timber-framed building at Bruchmauerstraße 37, standing on a footprint of 8.50 by 5.55 metres. Its roof begins at about 5 metres and has had a shallower pitch since the 1835/36 conversion. The upper floor did not cover the whole area but had an opening with a narrow gallery on the east side, probably the women's gallery reached by a west door and stair in the north wall.

Dendrochronology dated the building's timbers to 1632, establishing construction in 1633. In 1723 the Jewish community rented it from the musician Julius Hardewig Spangenberg, since Jews were generally barred from owning property. In March 1742 the shoemaker Johann Adolph Grote bought the plot, and the synagogue was moved from Bruchmauerstraße to Exterstraße. Descendants converted the rear building into two rental flats in 1835/36.

The space served as a gathering place for the Jewish community for generations. The half-timbered style was common for local buildings and made the courtyard feel intimate despite its small footprint.

Access to the building is limited as the structure is currently under protection and facing restoration work. Visitors should check ahead about which areas might be accessible and plan to view the exterior carefully.

Tree ring analysis confirmed the timber in the roof structure dates precisely to 1633, making it one of the oldest surviving Jewish religious buildings in the region. This scientific proof secured its recognition as a rare early example of a courtyard synagogue design in Northwest Germany.
