Pilgrimage Chapel St. Ottilien, Catholic pilgrimage chapel in Buttisholz, canton of Lucerne, Switzerland

Pilgrimage Chapel St. Ottilien is a baroque chapel on a hill near the hamlet of St. Ottilien, southeast of Buttisholz. Its plan is an octagonal central space with four polygonally closed cross arms, measuring 16 by 16 by 16 metres. Curved copper roofs rise into a small bell turret reaching 24 metres; a round-arched porch in one arm leads inside, with the sacristy above it.

The pilgrimage site's origins are obscure; excavations revealed the foundations of a medieval chapel. In 1572 the Lucerne bailiff Lüpold Feer had the chapel renovated and founded a brotherhood to maintain it. His great-grandson Hans Thüring Feer commissioned the present new building from Jost Melchior Zur Gilgen in 1669.

The chapel is dedicated to Saint Ottilia, whose legend is recalled in the oil-painted antependium of 1803 showing Emperor Charles IV taking her relics. The high altar holds a central statue of Ottilia flanked by Saint Jost and Saint Catherine, with a Madonna and Child above. Two obelisks on the altar contain votive offerings, and votive pictures decorate the side walls of the cross arms.

The chapel sits on a hilltop outside the village center and is easily reached by marked walking paths through the countryside. The peaceful location makes a visit on foot particularly pleasant.

The main altar inside features a statue of Saint Ottilia holding eyes in her hands, a rare motif in Swiss baroque art. Votive images covering the walls tell stories of pilgrim prayers and requests spanning centuries.
