Dating back to the 4th century, this Roman Catholic basilica stands on the site of a former Roman burial ground and is dedicated to Saint Gereon, a soldier martyred for his Christian faith. The church’s most striking feature is its ten-sided nave topped by a massive dome—considered the largest of its kind north of the Alps. Over centuries, the basilica has absorbed Roman, Byzantine, and Romanesque influences, resulting in a layered architectural masterpiece. Inside, visitors can discover remnants of ancient mosaics, medieval frescoes, and sacred relics that reflect its long spiritual legacy. Despite its central location, St. Gereon retains a quiet, contemplative atmosphere, offering a retreat from the city’s bustle. It is part of Cologne’s group of twelve Romanesque churches and remains a vital symbol of continuity, faith, and artistic achievement in the heart of the city.
Cologne GermanyBasilica of St. Gereon is located at Gereonskloster 2, 50670 Köln, in Cologne's Altstadt-Nord district, a short walk northwest from the Cathedral and central train station. Set on a quiet square, the basilica is surrounded by small parks, including the green space featuring the sculpted head of St. Gereon and tree-lined paths. The area is characterized by historic Romanesque churches and medieval streets, with the attractions of Cologne’s Old Town, such as the Cologne Cathedral, Roman-Germanic Museum, and the shopping district on Schildergasse, easily reachable on foot. Ebertplatz and Christophstraße/Mediapark transport stations are nearby, making the basilica accessible by tram or bus.
