Franziskanerkloster, Catholic pilgrimage church in Dettelbach, Bavaria, Germany

Maria im Sand is a pilgrimage church in Dettelbach, Bavaria, built between 1608 and 1613 under Prince-Bishop Julius Echter von Mespelbrunn. The church has a transept and a west facade whose portal was designed by Michael Kern of Forchtenberg. The west nave bay collapsed in August 1612 and was rebuilt with modified plans.

Pilgrimage at Dettelbach began after a miracle reported in 1505, when the paralysed Nikolaus Lemmer was healed at a wayside shrine east of town. A small wooden chapel was built around the shrine, and in 1608 Prince-Bishop Julius Echter von Mespelbrunn began the present church, consecrated on 8 September 1613 after the western nave bay collapsed in 1612. The building cost 15,000 gulden.

The pilgrimage dates to 1505, when the paralyzed Nikolaus Lemmer from Melkendorf was said to be healed at a wayside shrine east of Dettelbach. Abbot Johannes Trithemius described the wooden chapel built around it in his 1511 collection of miracles. The church remains the most important pilgrimage site in the Diocese of Würzburg.

A marked pilgrim path connects Dettelbach's town center to the monastery and is easy to follow on foot. The church is generally open to visitors without prior booking, and weekday mornings tend to be quieter than weekends.

Along the pilgrim path there are several old wayside shrines and a processional altar that have served as stopping points for travelers for centuries. Some of these stations feature carved woodwork made by local craftsmen over the years.
