Detail of the Roman gate from my previous post. The excavated foundations feature an inner bailey between two gates, possibly to trap attackers and attack them from above. Or maybe just to impress visitors to the city.

Stills from an animation about the Roman city of Cologne for the exhibition "Rom am Rhein".
