Judging by the wall anchors, the late Gothic chapel was built or renovated in 1617. In 1750 the chapel partly burnt down. The single nave chapel with polygonal chancel is made of bricks but the underside is cemented. It is oriented, which means it is East-facing, as a symbol of the resurrection.
The 17th century Baroque portico altar is made of marbled wood.
