II.2. Special features of planning connections: Access to the site is through an arched opening in the north-eastern (northeastern) wall; a second opening survives where a section of wall has been lost.

Memorial plaque is a cast-iron slab on the southeast wall read: “These are the remains of the walls of the former Akatuy labour camp. The Decembrist M.S. Lunin, Polish rebels, Narodnaya Volya plotters, sailors from the Prut transport, Kurnatovsky, and others were held in prison. The prison was built in 1832 and closed in 1917».
