Zülpich Castle

In 1285 the Archbishop Friedrich III. from Saarwerden demolish a castle that the Jülich counts had illegally built and instead build the Zülpicher castle with its mighty round towers.
The present castle dates from the 14./15. Century and is integrated into the city wall Zülpichs. Also well preserved are the four city gates: Münstertor, Bachtor, Kölntor, Weiertor.
They are part of the largely restored Wall Ring, which surrounds the historic center of Zülpich.
