Masonry fireplaces, rare in the medieval buildings of this region, are preserved in them. These furnaces were discovered during the archaeological surveys and each had its own chimney built into the walls. The toilet, specifically built for the commander of the fortress, was also discovered. Over city's moat lies a bridge which is located at the southeastern tower, and that leads to a space between the fortress and the low walls around it. On all the ramparts except the West one, the embrasures are placed at the same distance from the tower.
