It consists of a nave, which is closed off by a slightly indented 5/8 chancel and a small extension on the west side. The Italianate tower is integrated into the ground plan.
A natural rock juts into the building at the rear wall of the chancel.
The chapel is owned by the Ganter Burgschaft (not the church). The family coats of arms of the Ganter Burgschaft can be seen in the chapel.
