Typically for Franciscan monastery churches, it was built in the
Gothic style. It took from 1245 to about 1260 to build its early-Gothic choir, with a three-aisle nave added in the 14th century. As the Franciscans are a
mendicant order, they built a
ridge turret but no bell tower, indications of the poverty adopted by the order. When the French Revolution spread to Cologne in 1794, the Franciscans were expelled from the church and the adjoining monastery. The occupying forces seized the buildings in 1804 and four years later turned them into the headquarters for secular social work in the city. In 1846 the church was handed over to the city's
cathedral chapter for use as an annexe church to
Cologne Cathedral and four years later archbishop
Johannes von Geissel made it the diocesan church for confirmations and ordinations. He also instigated a restoration which was completed in 1862, partly thanks to a 40,000
Taler donation from the businessman
Johann Heinrich Richartz (1795–1861), who had already set up the
Wallraf-Richartz-Museum on the former site of the monastery buildings. == Organ ==
