Erentrudiskapelle, Chapel on Kapellenberg hill in Freiburg im Breisgau, Germany.

The Erentrudiskapelle sits on a hilltop near Freiburg and commands views across the surrounding landscape toward distant mountain ranges and the valley beyond. The structure from the 18th century holds religious artwork and furnishings that reflect its purpose as a place of worship.

A castle of the lords of Staufen stood on the Kapellenberg in the 13th century. A chapel is documented in 1520, 1573, 1580 and 1635; in 1713 it was destroyed during the War of the Spanish Succession and rebuilt under the hermit Melchior Rech and pastor Franz Benedict Ginter, consecrated in 1715/16. Hermits lived in an annex until 1843, and after decay the chapel was rebuilt in 1879 without that annex.

The chapel is dedicated to Saint Erentrudis of Salzburg, sister of Saint Rupert; she was wrongly confused with Saint Trudpert, venerated in the Breisgau. In 1748 the Salzburg monastery of Nonnberg donated a relic of Erentrudis, and in 1984 Abbot Franz Bachler consecrated a new statue modelled on a late-Gothic figure from Nonnberg.

The site sits on a hillside and can be reached on foot or by bicycle, with walking paths throughout the surrounding area. Visitors should note that this is a small chapel with limited capacity, so arrival times may affect the experience.

The chapel's 1750 altar by sculptor Matthias Faller held statues of Saints Trudpert and Erentrudis; these were given to the Augustinermuseum in Freiburg in 1926. The open roof turret received a small bell from the Neu-Ulm Grüninger foundry in 1949, tuned to b"+4.
