The tower is most likely a water tower, built by the Poles when their military unit was located here. There is a mark from the arrival of the projectile, most likely in the Great Patriotic War. It's a pity they don't build so well now. Not far from the tower there are two houses in which Polish officers were quartered, and in the building of the soldiers' barracks, which now belongs to the Central Hospital and houses, if my memory serves me correctly, the departments of 2nd surgery, urology and eye.
If this is a "landmark", as it says here, then you need to do something appropriate. In one part there were people who "took over" this place, in another part there was an eternally smelly and drunken artist (who eventually let a homeless man spend the night there, who set a fire and burned down). This part stands and stinks burnt out. So much for the "landmark"(((((
