The defensive walls of Pyrzyce were built in four stages, from the location of the town in 1263 - to the second half of the 19th century. 16th century Stage I - until 1301: the main ring of walls was built, along with lookouts and gates. Stage II - half 14th century: in place of two gates, the lower floors of two gates were built, and three lookouts were rebuilt into defensive towers. Stage III - 15th century: construction of three towers, reconstruction of gates and superstructure of walls. Stage IV - mid 16th century: expansion of the defense system, related to the popularization of artillery. Bastions, bastions, fortifications were built, and gates and towers were added. At that time, the defense system of Pyrzyce was finally completed, resulting in the construction of: defensive walls approximately 2,000 m long and 7-9 m high, with two gates and a foregate, 44 lookouts, 8 overhead lookouts, 6 towers (including two cylindrical). The city was surrounded by a double ring of embankments and moats - approximately 2,250 m long. The moats were irrigated after opening locks from four artificially created ponds, fed with water from Sicina (a tributary of the Płonia River. Until 1574, there were no invasions by Brandenburg, Polish and Hussite troops did not breach the Pyrzyce walls. After 1750, some of the embankments were planted, and in the years 1830-45 they were turned into a promenade. The moats were filled in around 1860, and gardens were established in their place. At the end of the 18th century, the foregate of the Banska Gate was demolished, and after 1854, the foregate of the Szczecin Gate. In the 19th century, the towers served economic functions (icehouse, workshop). The former lookouts were converted into residential houses for the poor. In the years 1835-1843, the damaged parts of the walls were renovated, in 1879, a fragment of the wall in the street axis was demolished Szeroka, and numerous gates for pedestrian traffic were pierced. During World War II, the Szczecin Gate and the Monk's Tower were destroyed, as well as the upper storeys of the towers and the Banska Gate. After 1945, the city fortifications were systematically renovated and preserved.
