The area of the fortress was soon built up to the limit, and some rooms were built outside the walls of the fortress. So, later formed the Upper forstadt-on the mountain, and in the Foothills-the Lower forstadt. Forstadt is a settlement where the main role is played by the fortress and the military. In the Lower forstadt there is a Cossack village, a hospital, and a locksmith's shop. For security reasons, the suburb was surrounded by a fence. The entrance and exit were guarded by special guards.
