The town of Choszczno (Arnswalde) was founded in 1291. Its brick fortifications were created in the fourteenth century, when granite and brick walls replaced the earlier timber palisades. In the fifteenth and sixteenth century fortifications were extended. From the beginning of the 18th century, the liquidation of the fortifications began. The earth ramparts and moats were leveled, leaving only their fragments from the south and south-west, and part of the towers were pulled down. At the beginning of the 19th century, the gates were demolished, and over time, houses and outbuildings were added to the remains of the defensive walls. The Second World War and post-war negligence brought further destructions.
The ring of fortifications was erected on a plan similar to the elongated rectangle measuring 400 by 600 meters, with a longer axis located on the east-west line. The total length of the defensive walls was 1,600 meters. It was strengthened with 7 closed towers and 36 half towers. In the eastern section of the walls there were five closed towers, in the south and west sections only one. Similarly, the half towers were unevenly distributed, the largest amount of which was placed from the east and west. The entrance to the town led through three gates: Stone Gate from the west, High Gate from the south – east and Mill Gate from the north. In the 15th and 16th centuries, the defensive walls were expanded. There were drawbridges and foregates, and the height of the walls increased to 8 meters. The fortifications were reinforced by a dual system of earth ramparts and moats, the northern side was also protected by wetlands.
Today, the main, preserved element of fortifications is the gothic tower from foregate of the Stone Gate, also known as the Barbican. The longest section of the 334 meters long wall is located on the north side. It stretches from Moniuszki Street to the Moniuszko Park. On the western side, three fragments of the wall and one directly to the south of Wolności Street have preserved. On the south side, between the streets of Bolesława Chrobrego and Władysław Jagiełło, only two farthest sections of the wall, located on the street Mur Południowy, have survived to a considerable height. To the south of the old wall line, however, the earth rampart has been preserved. Now the promenade runs along it. Only one small fragment of the wall on the southern edge has survived from the east. Six half towers have survived within the northern wall, fragments of two further in the western wall.
