Klauskapelle, Romanesque chapel in Goslar, Germany

The Klauskapelle is a small Romanesque chapel in Goslar, built as a rectangular hall church of rough rubble masonry. Its flat-roofed main room measures 10 by 7 metres, followed by a rectangular choir with groin vaulting and a round apse. The north wall holds the entrance and three Romanesque round-arched windows; the south wall, once part of the city wall, has no windows.

The chapel was first documented in 1186 and originally served as a gate chapel at the city wall. From 1537 onward it became a place of prayer for miners working at the nearby Rammelsberg mine.

The chapel is dedicated to Saint Nicholas, the patron of travelers and carriers, because it stood near the southern city gate. The dedication and location show how important this place was for people entering or leaving the city.

The chapel is not always open and visits should be arranged in advance. Guided tours are offered through the Frankenberg parish and provide insight into the place's history and purpose.

The chapel's north wall has two weathered reliefs, likely depictions of Saint Nicholas, set into the wall that continues the west wall. Inside, the altar holds a candleholder made of rich ore, while a second holder made of poor ore rests on a medieval ore carrier on the floor; both were made for the 1988 thanksgiving after the Rammelsberg mine closed.
