Walls of Trabzon, Trabzon

The Walls of Trabzon are a series of defensive walls surrounding the old town of the city of Trabzon, northeastern Turkey. The fortifications are sometimes called the Trabzon Castle. However, they did not function as a castle, rather as city walls. Constructed on foundations dating back to the Roman era with cut stones from former structures at site, the walls stretch from the hill on the backside of the old town to the Black Sea shore. The walls further divided the city into three parts; the Upper Town or "fortress", the Middle Town and the Lower Town. The upper and middle towns are flanked by steep ravines cut by the Zagnos and Tabakhane streams to the west and east respectively, while the lower town extends to the west of Zagnos. ()
