Like most medieval towns Lvov was heavily fortified. The internal wall with four corner towers was followed by an outer wall which had seventeen towers and was surrounded by a moat filled with water. Then came the ramparts and bastions along Valovaya Street, Square of Daniil Galitsky (Ploshchad Daniila Galitsga) . The town had two Gateways – the Galitsk and Cracow Gates, and two gates – the Yezuitslwya (near the church of the Jesuits) and Basatskaya (from the Russian “bosoi” meaning barefooted), at the end of Ruthenian Street which were used for communication with the Monastery of the Barefooted Carmelites (Manastyr Easy kh Karmelitav).
There was a time when these walls, ramparts and moats enabled the town to repel many sieges. But the years took their toll, and by the 18th century they were no longer a protection against artillery fire and other new means of warfare.
