Erasmus Chapel, Romanesque church and archaeological site in Bavaria, Germany.

Erasmus Chapel is a Romanesque church in Bavaria featuring rounded arches, thick walls, and substantial pillars typical of medieval construction. The building functions as both a preserved example of this architectural period and an active archaeological research site.

Built in the late 13th or 14th century as a cemetery chapel, it was first documented in 1313. A fire in the 14th century led to rebuilding with a brick barrel vault. In 1557 the profaned building passed to the imperial city, which converted it into a linen inspection house and wine cellar. The upper chapel was demolished in 1857 despite protests, and its foundations were rediscovered during World War II.

The lower floor, once a charnel house dedicated to Saint Erasmus, held bones moved aside when new graves were dug; the upper floor was dedicated to the Archangel Michael. After the cemetery moved to the Burghalde slope in 1535, the building was profaned and the ground floor became a linen inspection hall where Kempten weavers' cloth was checked and sealed with lead marks, while a wine cellar and drinking room occupied the lower level.

The chapel is located at coordinates 47.7253° latitude and 10.3196° longitude with parking areas near the entrance. Wearing comfortable shoes is advisable since the site and surroundings feature uneven terrain and walking is necessary to explore the full setting.

The chapel was demolished in 1857, but its foundations were rediscovered during World War II when a trench was dug and broke through the masonry. The lower Erasmus room's vault was smashed and the hole filled with rubble; the site opened to the public in 2010.
