St. Maria vom Frieden church and convent

Nestled inconspicuously between contemporary residential buildings is this impressive complex with gothic-inspired decorations

The church belonged to the local charterhouse (a monastery of the Carthusian order) until 1794, when the monastery was closed and the church was used variously as a warehouse or a military hospital until the 1920s, when it was restored to its religious function by a local Protestant community, whom it serves as a church until today. After reconstruction, it features an impressive pipe organ array with glockenspiel.

An early Romanesque basilica in the southern part of the Old Town, once serving as the church for a Benedictine abbey. It is dedicated to St. Pantaleon, St. Cosmas, and St. Damian. Sightseeing is restricted to times outside of religious services; information regarding public tours and group registrations can be found on the official website.

This Catholic church is one of the oldest in Cologne, predating even the famous romanesque churches, as it was founded in 948. It has seen many additions and reconstructions throughout the centuries, and was almost totally destroyed during the Second World War. Its current form is an eclectic reconstruction finished in the early 1960s.
