The castle was built in the cent. IV BC in the Illyrian period, rebuilt by Justinian in the 5th century and repaired in 1531 by Sultan Sulejmani. The castle has an area of about 3.6Ha and a height of about 380m above sea level. In the system of fortification walls there are several stages of construction. First we have construction traces of the Illyrian wall, in which we have used the square isodomic system. In late antiquity the technique of construction “Opus mixtum” was used. The early medieval period and beyond, is represented by the reconstructions and repairs of the surrounding wall. At this stage the wall is built with medium unworked stones as well as reused antique blocks, bonded with lime mortar. Also in this period we have the reinforcement of the surrounding wall with towers. Inside the castle there are traces of dwellings, as well as other construction elements such as roads, canals, terraces, etc
