The Lady Chapel on the hill above Osogna was built on the ruins of a medieval castle. It dates from the 16th century and has a rectangular floor plan with a choir. In the portal's lunette, which is surrounded by a stone frame, a Madonna and Child can be seen in front of a lovely landscape (mid-16th century). The image of the Madonna Enthroned to the right of the choir dates from the 15th century. The nave has an open beamed ceiling, the choir a barrel vault. The late Gothic fresco on the left wall of the choir depicts Saints Sebastian and Rochus. A baroque group of the Annunciation (17th century) is emblazoned on the triumphal arch. The fresco of the Assumption of Mary on the right side of the ship dates from the same period. The beautiful winged altar is the work of Ivo Strigel from Memmingen (1494); In the middle part the Saints George and Markus can be seen on the inside Jakob and Wolfgang, outside Christophorus and Anna Metterza. The chapel was restored in 1972.
