While excavating a 17th-century pilgrimage church, archaeologists uncovered a stout Roman fortress with five defense towers and walls more than 12 feet thick. The Roman citadel Boiotro was discovered on a hill known as the Mariahilfberg on the south bank of the river Inn, with its Roman well still plentiful and fresh. Pottery, lead figures, and other artifacts from the area are housed in this museum at the edge of the site.
