Gosudareva (Sovereign) Tower

The only one of all the towers of the fortress has a rectangular shape. And this is not just like that. The passage to the fortress is curved at a right angle, so much, that the enemy breaking through the gate is usually positioned with his right unprotected side (his shield is in his left hand and his sword in his right) towards the loopholes of the fortress wall. The tower has 4 tiers and, according to some reports, a spacious basement.
