Minor Maximillian Tower No. 3

The fort was connected with the court of the Citadel by way of a wooden drawbridge extended over the fort's dry ditch. When drawn up, the body of the bridge covered the gateway of the main entrance, while a cistern of water located under the bridge presented an additional obstacle.

In the construction plans, the tower presents a nonagon with vertical walls of unplastered red brick. Spatially the tower consists of two levels above ground, and two additional levels below ground, located under part of the building, and concludes in an open terrace. The spiral staircase providing vertical communication is located in a central cylinder, which extends to the terrace and concludes in a cupola vault. The main entrance to the tower is located at the level of the first floor, and proceeds through a drawbridge from the side of the Citadel's court. The planning structure of the first floor is formed by the main entrance, the corridor which circled part of the staircase and extended on both sides to the great hall, which occupied five crosspieces of the external wall and functioned as the soldiers' living quarters. The radial walls of the main entrance enclosure had four slanted battlements for light weapons, and an additional battlement was situated in the stem of the staircase. A room to the left of the entrance held a water-closet, which is evident from the outlets of brick wells, both inside and outside in the moat of the dry ditch.

The corridor also provided access to two more living rooms, encircled by radial walls and located to the right of the entrance. The cellars of the small towers were used to store ammunition and supplies, and, apart from the radial corridor, also consisted of three small and one larger room. The cellar's floor held a round hatch leading to another even lower level, which held a cistern with water. The second floor held a single circular hall for the artillery battery, where heavy cannons were stationed on wheels. To slow down the recoil during shooting, the cannons were attached to a latch by means of a vertical finger. The latch was built into the wall under the large battlement. A hook in the intersection of the vault held a structure for raising up cannonballs for the cannons. Above the center of the room, another hook was mounted into the vault to hold lighting lamps.

The vaults of the vestibule of the main entrance, as well as the floor of the second level had a rectangular hatch to allow raising cannons up. The raising mechanism was mounted in the tower's upper terrace.

The smaller size of these forts is due to the fact that this portion of the Citadel was better protected overall, as well as due to the close location of the two artillery towers of the central redoubt and the presence of two natural obstacles – the Pelchynskyi and Panienskyi ponds at the foot of the Pelchynska Hill.
