The shape of the Samuil’s Fortress dates back to the time of Samuil, although there are also data about demolitions and repairs of the fortress by the Turks and Byzantines. It features walls with a height of 10 to 16 metres and a thickness of several metres. On all sides, with the exception of the south, which is facing the lake, the hilly part of the city was protected by high walls and towers, three kilometres long, near the port of Ohrid. With its fortifications and walls it covers the entire Ohrid Hill. Today, 18 towers and four gates are preserved on the fortress. Parts of the fortress extend to the lake and to the lower hill of the old part of Ohrid. In the old part of the city, there were three gates, from which only the Upper Gate was preserved. Many stones with Greek inscriptions are built in its walls. Under a partially demolished outer layer in the inner walls, horizontal layers of bricks of Byzantine format are noted.
