Fridolinsmünster Bad Säckingen, Religious monument in Bad Säckingen, Germany.

The Fridolinsmünster is a church in Bad Säckingen with a pale pink and cream facade outlined in red and two tall towers, each with a square stone middle section and a green copper dome; the right dome carries a cross, the left a small sphere. A clock and a golden figure sit between the towers, and the red-framed main portal is flanked by two painted figures below a statue in a niche. The lower facade is painted, the upper part open brickwork.

The oldest surviving part is the 11th-century crypt of a three-nave basilica; in the 12th century a twin-tower west front was added. After a devastating fire, the church was rebuilt between 1343 and 1360 and consecrated by Konstanz bishop Heinrich III von Brandis on 21 December 1360. Fires after French troops entered during the Dutch War led to a Baroque rebuilding by Michael Widemann of Elchingen between 1698 and 1701, and after a 1751 organ fire the nave was renewed by 1753.

The church is dedicated to Saint Fridolin, whose relics rest in a silver shrine in the Fridolin Chapel, open to the public on the right side of the choir. A procession on the Sunday after 6 March, his feast and death day, draws visitors from beyond the region. The church is listed among the "Mythical Places on the Upper Rhine" for its legends.

The church is open to visitors year-round and can be viewed from inside. Access is partially arranged for people with mobility needs, though some areas may require extra effort to reach.

The church sits near the Rhine River, giving visitors a place to sit with views of the flowing water nearby. This location makes it a special spot where religious space and natural landscape meet.
