About St. Gereon's Basilica
St. Gereon's Basilica is a Roman Catholic church in Cologne. It is dedicated to Saint Gereon and became a minor basilica on June 25, 1920. Its core preserves an oval central structure with nine cones, Roman work from between 350 and 365. That lower part of the present decagon is one of the key examples of ancient representational architecture north of the Alps and counts among Germany's oldest surviving sacred buildings.
A church dedicated to St. Gereon here is first documented in 612. Archbishop Hildebold added a rectangular choir around 800. From 1151, the choir gallery, apse and transepts were added under Archbishop Arnold II von Wied. Between 1219 and 1227 the ancient mausoleum was strengthened and given an outer sheath, turned into a decagon, raised, and given Gothic galleries and a central dome.
Its decagon dome, late Romanesque and early Gothic, was the largest dome in the West between the 6th-century Hagia Sophia and the 15th-century Duomo of Florence. The nave lies under an oval decagon dome, 21.0 m in length and 16.9 m across, finished in 1227 on the antique central building's remains. St. Gereon belongs to Cologne's twelve great Romanesque churches.
