It is notable for containing the tombs of Duns Scotus and Adolph Kolping, both of whom were beatified by Pope John Paul II - Kolping was also ordained priest in the church. Kolping and Scotus both feature on the new west doors designed by Paul Nagel in 2006.

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.

A new Romanus Seifert & Sohn organ was installed in 1997, with 44 registers, divided into three manuals and pedals, with mechanical trackers and electrical registers. The expression pedal is equipped with Barker levers.

The ridge-turret houses two bells, both cast in Münster by Feldmann & Marschel. They replace two bells cast in 1754 and 1853 which were destroyed during the Second World War.^[1] As with the 'Kirchen am Neumarkt' (St. Aposteln, the Antoniterkirche and St. Peter), both bells ring at 16:45 on Saturdays and Sundays, whilst the 'Marienglocke' rings the Angelus on its own at 19:30 each evening.
