Construction of the church, originally intended as a monastery church, was begun in 1272 by the
Franciscan Order. It was completed and consecrated in 1307, dedicated to
Louis of Toulouse. In 1806 the church was taken over by the parish of St. Remigius, after the church in that parish was struck by lightning in 1800. The building was damaged when Bonn
came under siege by Brandenburg troops in 1689, and was damaged by a fire in 1888. It again suffered damage during the Second World War. From 1957 to 2007 it was again a monastery church under the care of the Franciscans. In 2006 the independent parish of St. Remigius merged with the parish of St. Martin. ==Association with Beethoven==
