Bonn Minster

The origins of Bonn Minster stretch back considerably. Archaeological discoveries such as altars dedicated to Roman gods and a necropolis from the 2nd century indicate an early cult site at this location. In the 6th century, an initial hall building was erected, serving as a burial site for Merovingians. By the late 7th century at the latest, clerics settled nearby. At the end of the 8th century, the Cassius Collegiate Foundation was established here, and the collegiate church of St. Cassius and Florentius was built. Around 1050, the old collegiate church was demolished and replaced by a Romanesque new building, a three-aisled cruciform basilica with a double choir arrangement. Following the secularization of the foundation in the early 19th century and the demolition of the adjacent parish church of St. Martin, the Minster came into the possession of St. Martin's parish. Since 1956, it has held the title of a Basilica minor.

Bonn Minster is centrally located in the city of Bonn, which is situated in the federal state of North Rhine-Westphalia in Germany.

Bonn Minster is protected as a historical monument in North Rhine-Westphalia and underwent extensive renovation from 2017 to 2023. It continues to serve as an active Catholic church.
