Stefanyk Library storeroom (Maximillian Tower)

The tower was planned as a regular 17-gon with a circular inner courtyard. A dry ditch and an earth bulwark with a supporting wall present the external defensive system, which makes access to the fort difficult and shields the first, living level of the building from enemy fire. The bottom of the ditch is paved with sandstone plates. A drawbridge was built over the ditch, which, when drawn up, covered the entrance gate and the battlement above it. The bridge could be drawn up with a chain mechanism, located in the rooms of the first and second floors. The tower consists of two levels, as well as a cellar and an attic. Construction of the levels was planned as a system of corridors with enfilades connecting some of the first level rooms. The windows of the circular corridors on both levels overlook the internal courtyard. The staircase, which is semicircular from above, extends into the internal courtyard. The balanced stairs between the levels consist of a single flight. The façade that holds the portal of the main entrance has a niche, concluding with an arc. The vestibule/?тамбур by the entrance section, as well as the partitions between the cellar, the first and second levels exhibit quadrangular apertures that form a vertical shaft for passing cannons and ammunition. The terrace of the tower formerly held a mechanism for this purpose. On the level of the terrace, the aperture of the vertical shaft is framed by whitestone with grooves to allow installation of a metallic double-pitch rooflet.
