Brüdernkirche Braunschweig, Gothic church in Brunswick, Germany.

Brüdernkirche is a Gothic church in Brunswick featuring towering stone walls, pointed arches, and decorative stained glass windows. The windows cast colored light across the interior, creating distinct patterns of illumination throughout the worship space.

Franciscans reached Brunswick around 1223 and built a chapel from 1242; the present Gothic church replaced it, with the high choir consecrated in 1361 and the building finished in 1451. Johannes Bugenhagen preached here on 21 May 1528, and the town council adopted the new church order that September. The friars left in 1529, and in 1544 the church became the parish church of St. Ulrici.

The name Brüdernkirche comes from the Franciscan friars who settled here in the 13th century. Since 1544 it has been the parish church of the St. Ulrici congregation, whose baptismal font was moved here from the demolished St. Ulrici church on the Kohlmarkt. Inside, a 14th-century choir stall, the high altar and a relief of St. Francis survive, and the partly preserved rood screen of 1592–1594 has been re-erected.

The church stands at the northern edge of the old town, its west portal reached through a three-part neo-Gothic porch. The interior is 62 metres long and the nave 21 metres wide, so allow time to walk the five bays and the 25-metre choir. Parts of the medieval cloister, sacristy and a small chapel survive alongside the church.

The church keeps a 14th-century choir stall, the high altar and a relief of Saint Francis. Its partly preserved rood screen of 1592–1594 has been re-erected, and the font comes from St. Ulrici, demolished in 1544.
