Zülpich Town Fortification

The origins of the town wall date back to Roman times, as parts of the medieval ring wall were built on the foundations of a Roman fortification. In the 14th century, the current complex was created along with four town gates. A detail at the Frankengraben is a piece of a Roman aqueduct that once led from the Eifel to Cologne, uncovered in Mechernich-Breitenbenden in 1979 and re-erected here. The Kölntor, a double gate in the east, was built at the end of the 14th century. It was enlarged in 1886 and repaired between 1949 and 1953 after war damage.
