Tumlu Castle is an Armenian castle built in the 12th century. The handsome structure sits on a limestone outcrop ca. 150 m high. The Armenians were not the first to occupy the place as fragments of a Roman pottery, dated to the 1st and 2nd centuries AD, were found in situ (Pekol 2015). Within the stronghold's solid walls a garrison was stationed which protected an auxiliary trail from modern-day Imamoğlu town to the Kozan-Ceyhan road (Edwards 1987). The castle underwent restoration works in 2014-15 that had to be halted due to safety issues (Pekol 2015). At the time of my visit there was no tourist-friendly access to the interior. To get inside I climbed up an almost vertical rocky wall and squeezed myself through a postern in one of the towers.
