The Seelenkapelle (Chapel of the Souls) is one of the few buildings in the center of Oberstdirf, which did not fall victim to the Great Fire of 1865. The chapel is located on the west side of the parish church - in the middle of the old abandoned cemetery - and has been used as a war memorial chapel since 1931. The entrance is therefore guarded by two martial soldiers.

The chapel was probably built in the late 15th century. An "eternal light" was donated to it in 1504. In 1524 it was mentioned as an ossuary. The amazing paintings with the sculptures in the niches on the north wall were created in the middle of the 16th century. The impressive Pietà in the interior is dating back to the early 40s of the 20th century.

The Seelenkapelle is of huge significance to the fallen soldiers from the war and is also considered as a memorial. The chapel is the second oldest of the Oberstdorf chapels.
