One of Seven Twin-Tower Gates
The structure was one of seven twin-tower gates in the city's fortifications, setting it apart from the others, which were central-tower gates with side terraces — the type seen at the Friesentor and Severinstorburg. The Gereonstor had three storeys, rounded flanking towers, and an outer and inner gate with a gatehall between them. The medieval machicolations along the upper battlements suggest construction began around 1215; Cologne's city gates are generally considered complete by 1260.
Name and Early Records
The gate is first attested in 1259 and appears in a document of June 1401 as „poerthen …off Sente Gereon." In medieval Latin it was known as „Porta Sancti Gereonis." The area on the city side of the gate remained largely uninhabited well into the late Middle Ages.
Ornament Without Traffic
The Gereonstor is among the oldest gates in the city wall and was likely conceived as a decorative feature from the outset. With no direct road connection, it was bricked up for over 400 years; only a narrow, low postern was left in the wall, and that was usually kept locked. The closure on the city side probably dates to the 14th century. Arnold Mercator's 1570 panorama of Cologne already shows the gate sealed and labels it „S. Gereons loch" — St. Gereon's hole.
The City's Strictest Prison
The gate later served as a city prison — as did the Hahnentor and Bayenturm — until the 18th century, and was reputed to be the harshest in Cologne. Mercator's nickname „S. Gereons loch" reflects this, since prisons were commonly called „Löcher" (holes) at the time. One of the six cells could only be reached by rope through the warden's kitchen. Serious criminals were known in Cologne as „Kettenmänner" — chain men — because they were shackled with heavy irons. Torture was practiced here; a thumbscrew from that era survives in the Cologne City Museum. In 1683, Colonel Gerhard von Kiberin was held here as a political prisoner during the Gülich Revolution before the prison was stormed and he was freed.
Re-Opening and Demolition
The Gereonstor was not reopened as a passageway until 1830. On 22 September 1871, returning Prussian troops marched through the gate toward the Neumarkt. The city fortifications belonged to the Prussian military treasury; after the City of Cologne acquired the fortress grounds in 1881, the gate was demolished that same year.
