The fortified city on the saddle between two hills. It had a steep double acropolis with fortification walls. The main gate had three successive entrances and two internal square courtyards so as to control the incoming. At this point started a street with almost eighty steps, which led up to the Agora. On its north side was a wall with towers, and private houses built on successive terraces, so that the roof of the lower ones was the actually the court and the way of access to the upper ones. These houses and others in the area of the north acropolis were simple in plan, usually with two square rooms having a hearth at the centre. Subterranean cisterns, cut in the rock were used for the collection of rain water for the needs of the household. Industrial workshops, such as an interesting dyehouse were located on the south side of the street.
