Small Staircase Descent is a part of the outer fortifications on the Sava slope. On the top it is connected with the counterguard in front of the Royal Ravelin, and at the bottom with the bastion of the Dark Gate. It represented the internal defended fortress communication that was partition with three caponiers. Due to the large slope, along the entire communication is the staircase with vaulted passages through caponiers. The reconstruction works of the Small Staircase Descent was completed in 2010.
