Aachener Tor, Medieval gate in Bergheim, Germany

The Aachener Tor is a medieval stone gate in Bergheim that served as the main passage into the town's oldest quarter. The structure displays typical defensive features with thick walls and a narrow opening designed to control entry.

The Aachener Tor was built in the 14th century as a two-storey double-tower gate with a pointed-arch passage. It was repeatedly damaged in the 16th and 17th centuries and converted into a prison around 1800. Renovations followed in 1911–1914, 1925, 1959 after a 1956 fire, and 1980/81; a full restoration took place from 2013 to 2017, costing about 2.3 million euros.

The gate is the landmark of Bergheim. Since 1947 it has served as the home of the Bergheim scouts, the Stamm and Hag Nibelungen, who belong to the Deutscher Pfadfinderbund and still use the building today. Above the field side, the side facing away from the town, a richly carved coat-of-arms stone shows a lion.

The gate stands on the northern edge of Bergheim's pedestrian zone, where the town wall meets it directly. The footpath through the right flank tower was added later, so the passage is narrow. The gate has been the home of Bergheim scout groups since 1947.

The gate's name recalls the road to Aachen, but the structure has served as the home of Bergheim's Boy Scouts since 1947. The groups Stamm and Hag Nibelungen, part of the Deutscher Pfadfinderbund, still use the medieval gate today.
