These are small fortresses with corrugated walls. They are built on earthen ramps inclined at a 75-degree angle. The architecture of the walls resembles corrugations formed by interconnected semi-circular or polygonal pilasters. The small-sized external windows are hidden within the folds of the walls. At the top, the walls are finished with crenellations, which have been mostly lost. The corrugation of the walls is made up of four-sided semi-cylinders, and the original height of the building is marked by stepped crenellations. The vaulted rooms on the first floor, which are currently inaccessible due to debris, were illuminated by five windows located on the southern wall. The descending staircase, also currently inaccessible, passed through a vaulted arched corridor. The building can only be entered through gaps in the northern or eastern walls, where there may have been entrances to the keshk.

The Small Kyz-Kala is located approximately one hundred meters south of the Great Kyz-Kala. Despite being relatively small in size (22x22) and less well-preserved, it was built according to the same plan as the Great Kyz-Kala. The corrugated facade has only survived on the southern and eastern sides of the structure. The corrugation consists of a series of semi-circular protrusions, and the spaces between them on the surface of the facade are wider compared to the Great Kyz-Kala. Windows are placed between the relief projections of the walls, which are mostly connected to the first floor.
