City walls were erected by Bolko I Świdnicki at the turn of the 13th and 14th centuries. They are first mentioned in 1336. In 1428 they were severely damaged during the Hussite invasion. In the fifteenth centurie, they were rebuilt in connection with the popularization of artillery and as a result of damage caused by the Hussite invasions. Their thorough renovation was carried out by prince Charles I in the first half of the 16th century. In 1780, on the order of Fryderyk II, the town moat was filled, and the area obtained in this way was designated for gardens. The demolition of the town walls began in 1819-1850.
A ring of fortifications established on a plan similar to an oval. The height of the defensive wall was up to 12 meters. It was strengthened with numerous semicircular half towers. Access to the town was secured by two moats, towers and five gates: Wrocławska, Zamkowa, Nyska, Paczkowska (Paczków Gate) i Tkacka also called Mill Gate.
The best preserved fragments of fortifications are located in the eastern part of the town. Paczków Gate, founded at the end of the 13th century, has also survived.
