 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.
