Example Input: Question: Which of the two saints that the church in Bronnen was dedicated to became a saint first? Passage:A church in Bronnen was first mentioned in the 12th century. In 1520 it was dedicated to St Margaret and in 1584 also to St Blaise. The core of the current building is Late Gothic but was converted to Baroque style in the 17th and 18th century. In 1658 a tower was added, followed by new panelling in 1667, and Apostle figures in 1672. The interior was further reshaped in Baroque and Rococo styles between 1711 and 1721 and again between 1731 and 1737 with contributions by painter Martin Weller from Ehingen and sculptor Dominikus Hermenegild Herberger from Dietenheim who created a processional cross and statues of the St Blaise and St Margaret. Between 1869 and 1868 the church's interior was redesigned in Neo-Romanesque style during which most of the Baroque and Rococo interiors were removed. In 1933 the nave was extended and a sacristy was added. In 1997 and 1998 the whole structure was renovated.
