Sankt Foillan (St. Foillan's Church), Aachen

Saint Foillan Church is dedicated to an Irish missionary saint known under several names, including Foillan and Feuillien. It is the only church in the German-speaking world with this dedication, which suggests that early Christian influence here came from western regions. The church stands very close to the cathedral complex, with only a narrow passage separating the two buildings.

The first church on this site was built around 1180 and was one of the earliest parish churches in the area. It was replaced by a larger three-nave Gothic church, consecrated in 1482. Only a few parts of this late medieval building remain today, such as sections of the choir and parts of the façade. Much of the exterior, including the tower, dates from 1888 or later. In 1944, a bombing raid almost completely destroyed the church.

Between 1956 and 1958, the church was rebuilt, and the remaining Gothic parts were reused with modern construction methods. Inside, the blue stone altar from 1962 stands in the center of the choir, surrounded by reliefs with 32 scenes from the story of Salvation. Above it hangs a bronze crucifix from the same year. Another important artwork is the Soft Style Madonna from around 1410, known for its calm expression and gentle forms.
