St. Cosmas and Damian, Catholic church in Volkhoven/Weiler, Germany.

St. Cosmas and Damian is the Roman Catholic parish church of Cologne-Weiler, completed in 1925 in neo-baroque forms on Regenboldstraße. The rendered facade with its steep slate pyramid roof and cross finial fronts a flat-barrel-vaulted interior; the side aisles have flat coffered ceilings and the choir ends in a semicircular apse. The tower was completely rebuilt in the 1960s after structural damage.

The parish was incorporated into Cologne's Kunibertsstift by Archbishop Friedrich I. von Schwarzenburg, a gift of the brothers Regenbold and Wezelo. The Romanesque church was replaced in 1766 by a plain Baroque brick hall with a west tower. The parish was suppressed under French occupation and restored in 1824. The larger neo-Baroque church on Regenboldstraße was completed in 1925, and its tower was rebuilt after structural damage in the 1960s.

The church takes its name from Saints Cosmas and Damian, two figures honored in Christian tradition as healers and protectors of the sick. This choice of dedication shows how local communities expressed their values through the saints they selected to honor.

This is an active worship space where regular Catholic services take place for local residents in the Volkhoven district. Visitors should check service times before visiting to find the best moment to experience the church at its fullest.

The organ now in the church was built in 1910 by E. F. Walcker & Cie. for the Protestant church in Leuscheid, with 16 stops on two manuals and pedal. Sold to the Weiler parish in 1964, it was restored by Gebrüder Stockmann in 2007 and returned to its 1910 disposition; it was rededicated on Easter Sunday 2007.
