Felsenkapelle Gschlößtal, Cave chapel in Matrei in Osttirol, Austria.

The Felsenkapelle Gschlößtal stands at about 1690 m on the left bank of the Gschlößbach, between Innergschlöß and Außergschlöß. A fieldstone facade with a pointed-arch portal, two pointed-arch windows and a round window is built against a large rock block; a short stone-roofed gable and a stone tower with three pointed-arch sound windows and a cross on its flat saddle roof rise above it. Inside, the natural rock was enlarged into a barrel-shaped stone vault, with plastered walls, natural stone floor slabs and a raised apse holding a wooden altar.

The structure was built in 1688 by Alpine residents, but had to be relocated in 1870 into a natural cave due to avalanche dangers. This relocation preserved the sanctuary from the elements and ensured its survival to this day.

The interior holds a wooden altar with dark marble, an 18th-century painting of Archangel Michael, and an alabaster figure of Mary beneath a crucifix. These religious objects reflect the devotion of people who sought spiritual solace in this remote location.

Visitors reach the chapel via a hiking trail from Gschlößbach bridge with around 200 meters of elevation gain on marked paths. The ascent takes several hours and requires sturdy footwear and good fitness for the mountainous terrain.

The chapel's tower facade of field stones was built in front of the rock block, so the masonry only closes off the natural cavity. Inside, the rock itself forms a barrel-shaped vault, plastered only up to the springing. The wooden altar holds a standing cross from the late 19th century and a Trinity image in the upper section.
