Saint John the Evangelist Chapel, Medieval chapel in Stainach-Pürgg, Austria

Saint John the Evangelist Chapel is a Romanesque chapel on the Kalvarienhügel in Pürgg, part of Stainach-Pürgg in Styria. It consists of a plain hall about 11 by 6 metres with a narrower, lower square choir to the east, built of squared stone blocks. The interior is almost entirely covered by frescoes from the third quarter of the 12th century.

First documented in 1350, the chapel is thought to be the surviving remnant of the Traungau family's Graunscharn castle and may predate 1120. After the dynasty died out in 1192 the castle was abandoned and the chapel likely became a memorial chapel. In the Baroque era it served as a Calvary station, and a small roof turret was added on the west side.

The frescoes, painted in the third quarter of the 12th century, cover almost the entire interior. A painted curtain forms the base zone; above it, the north wall shows the miracle of the multiplication of the loaves and the south wall scenes of Christ's birth. At the western end appears the profane fable of the war of the cats and the mice after Aesop, and in the ornamental band around the triumphal arch the word Allah is repeated in Kufic script.

The chapel stands on the Kalvarienhügel above Pürgg, reachable on foot via marked paths from the village. The terrain is a wooded hill; sturdy shoes help on the climb. The interior is a single small room with a flat-ceilinged choir, and the three crosses on the south wall mark the Baroque Calvary station. There is no visitor infrastructure at the chapel itself.

In the decorative band around the triumphal arch, the word Allah appears repeatedly in Kufic script among arabesques, slightly distorted. The chapel also shows the fable of the war between cats and mice after Aesop at the western end of the main fresco strip, a secular motif beside the biblical scenes.
