The Acropolis of Pergamon becomes rough to the north of the sacred enclosure of Trajaneum. Urbanization level was always low in this area, reason why no artificial terracing are observed and yes abundance of boulders, slopes, etc. The most relevant one that we can be seen here are some curtains and towers of the twelfth century Byzantine wall (photos 1 and 2) with its characteristic masonry type: moderately carved and placed in rows regularized with brick scraps. We also look at the foundations of the Pergamon Arsenal (photo 3), erected in the time of Atalo I to store the weapons of the city garrison and the food necessary to feed it in case of siege.

The acropolis of Pergamon concludes in this spot in the form of vertiginous cuts with a much more pronounced slope than that of the southern slope. Below, in the valley, flows smoothly the stream of the Keitos river, somewhat dammed at this point (photo 4). We decide, then, to back on our steps towards the area of the Trajaneum and the fabulous structure that we have deliberately overlooked on our visit: the famous Hellenistic theater of the city.
