Chojna – city defensive walls


   The oldest fortifications surrounding the old town were probably built already in the second half of the 13th century, but the range of these original fortifications could not be clearly determined. At the beginning of the 14th century, Chojna (Königsberg) was one of the main border strongholds of the New March, and then the town defense walls were created with a range that is still visible today. They were erected from stones and then gradually replaced with brick walls. The final architectural form and arrangement were given to them at the end of the 14th century and during the 15th century, during the reconstruction of the town after the invasion of the Szczecin prince Kazimierz III. The whole system of fortifications consisted of curtain walls, in which several dozens of towers and three gatehouses with extensive foregates, and earth ramparts and moats powered by the waters of Sarbica were situated.
In order to maintain the fortifications in proper condition and to defend the town, representatives of particular crafts were required, gathered in guilds, who had undergone appropriate military training. In case of a strong threat, they were supported by the remaining population of the town and allies (since 1320) from: Mieszkowice, Moryń and Trzcińsko, as well as the army of Brandenburg rulers, and in the years 1402-1454, the Teutonic Order military units.
In early modern times, due to the widespread use of firearms, town walls have lost their importance. The wars waged through the territories of the New March had a negative effect on the town fortifications: the Thirty Years War from 1618-1648 and the Seven Years War from 1756-1763. In the 18th century, extensive foregates were pulled down, moats were filled with earth from the embankments and gardens and alleys were created in their place. In the 19th century, one of the three gates was demolished.


   The defensive walls were built of brick on the stone foundations. Initially, it was a construction erected only from stones, modernization and brick superstructure began in 1316 and finished around the mid-fourteenth century. New fortifications were built of hand-made, gothic bricks. In the wall face, Flemish and monk bonds were used. The decorations of walls and towers in the form of diamonds, made of brick “zendrówka” are still noticeable today. The length of the circuit was significant, as it was almost 2,000 meters long. The thickness of the defensive walls was 1.5-1.2 meters in the most endangered places (fragments adjacent to the gates), and in places of lesser danger, protected by water and marshy area of ​​0.5-0.6 m (the northern section of the fortifications). This dimensions refer to the lower parts of the wall, as it narrowed gradually upwards and had a width of one brick, that is 28-29 cm. The original height of the wall oscillated around 9.5-9.7 meters. The entire circumference was probably crowned with battlement. The town side of the fortifications was also equipped with a underwall street, serving the town’s defenders to move quickly in the face of assault.
   In the 14th century, the defense walls were reinforced with half towers, open from the town side. Originally there were about 60 of them. In the fifteenth century, due to the wider use of firearms, cylindrical towers began to be introduced into existing walls and some half towers were modernized, by increasing and closing their rear parts. The most impressive of them was built at the beginning of the 16th century, the Pietruszkowa Tower (Petersilienturm) with a base measuring 8.2 × 5.8 meters. Another significant point of defense was the Prison Tower (Billerbeckturm), also known as the Gunpowder Tower. It was placed in the northern section of the walls, in the second half of the fifteenth century. It consists of three floors. In the first one there was once a prison for common criminals, while the second and third (equipped with arrowslits) performed typical defensive functions. The outer side of the tower was built on a half-circle plan with a radius of 2.5 meters, while the urban side (decorated with two rows of pointed blendes) on a rectangular plan with dimensions of 7.3 × 3.9 meters. On the outside of the tower, at the level of the third floor, the latrine was placed. Tower was topped with a brick cone and viewing platform, formerly serving defense and guard functions. The total height of the building is 16.8 meters.
   In the southern part of the walls there is the Bakery Tower, built at the beginning of the 15th century. It was made of the walls of the 14th-century half tower. It is two-storey, based on a square plan of 5.2 × 5.4 meters. The walls, 0.8 meter thick, were made of gothic brick and foundations made of stone. The main elevation of the urban side is decorated with three ogival blendes, while the side walls are decorated with single, twin blends. In the façade of the second floor of the outer side, three slotted arrowslits are visible. In the western side wall there is a well-preserved latrine. The tower owes its name to the bakers’ guild that takes care of it. The same name bears the street, perpendicular to the tower, where the representatives of this profession were probably once inhabited.
   In the close vicinity there was the Monk Tower, founded on a square plan with dimensions of 4.9 × 4.95 meters. The form of a closed tower also had a Little Powder Tower (Klein Pulverturm) located near the south-west corner of the fortification. It was founded at the end of the fifteenth century with a destination for the storage of gunpowder. Built on a circular plan, originally two or three-storey, it was covered with a conical hip roof. The thickness of its walls is 0.6 meters. Right next there is the Tower at Barnkowska Gate (Turm bei Bernikower Tor). It was the original half tower, later transformed into a closed one. It was built in the 14th century on a rectangular plan of 6.7 × 3.4 meters. It was a three-story building, set on a stone foundation. In the fifteenth century, the third storey was superstructured, and in the next century, the tower was closed by bricklaying the open to town side. From this period comes a late-gothic fireplace inside the second storey. In the fourteenth century part, four arrowslits were placed from the outside, while in the fifteenth-century part, three windows.
   Nevertheless, important tasks were fulfilled by half towers, built on the plan of a rectangle. Currently, we can count eleven such towers. To the more interesting and impressive should be included Stork half tower. Its first two floors were built in the fourteenth century, the third was added in the sixteenth century. The tower was built on a rectangular plan with dimensions of 4.95 × 2.8 meters. Two slotted arrowslits were placed in the outer façade of the second floor. One such arrowslit was located on both side walls of this floor. In the third storey of the front wall of the superstructure, two openings have been placed, and two rectangular openings on both sides of this storey. The town’s side of the tower is open, finished at the height of the second floor with an arcade.
   Three gates led to the town: Świecka, Barnkowska (Myśliborska) and Czworokolna, also known as Mill and Szczecińska (Vierraden). Made of brick laid in the monk bond, were prisms with centrally located gate passages. The tops could had battlements or timber roofs. In the fifteenth century, they underwent vertical expansion.
   The Świecka Gate is built on a 9,8 × 9,5 meter square plan. The lower stage with a wall thickness of 2.2 meters, has five floors. At the first and second level of defense, four niches with arrowslits are placed. On the third level you can see squinches, with the help of which the angular part goes into an octagonal part. The octagon has three levels, topped by a platform with a cone. All levels had ladder connections. There are separate staircases leading to four corner turrets, without connection to the octagonal part. On the side of the Świecie Gate there is a well-preserved latrine. The gatehouse front elevations are richly decorated with plastered ogival, trefoil blendes and friezes.
   The Barnkowska Gate also represents a two-stage form, it is a six-storey building, erected on a square plan with dimensions of 9.6 × 9.2 meters. The lower stage of the building has the form of a four-storey rectangular prism with a height of 15 meters. The external and town façade is richly decorated with plastered blendes. The gate’s passage is flanked by two high buttresses with a visible guide on the portcullis. On the inner walls of the gate passage two recesses are visible, used to fasten the log, protecting the portcullis or doors. In the upper part of the lower step there is a well-preserved latrine. The mass of the lower step is crowned with a viewing platform surrounded by battlement. The second stage of the building is an octagon, ending with a cornice, a polygonal crenel and a ceramic conical helmet. Also numerous slotted arrowslits are visible. The total height of the gate is 29 meters.
   The third gate in the system of the medieval fortifications of Chojna was the Czworokolna Gate, located in the northern part of the town. Established probably at the beginning of the fourteenth century, the information about its demolition and the construction of a new building in its place, dates back to 1430. It was a gable type gatehouse, covered with a ceramic gable roof. In the 15th/16th century, town gatehouses received a foregates combined in a defensive complex with a system of ramparts and moats.
   The outer zone of defense was the irrigated moat and earth ramparts. The whole town was surrounded by swamps, wetlands and floodplains of the Rurzyca River and the streams of Sarbica and Wrzośnica, flowing alongside the town, including Crow Marshes (Krähenbruch), stretching at the south-western section of the walls.

Current state

   In Chojna, defensive walls have been preserved in about 50 percent, including two gates: Barnkowska and Świecko, eight closed towers, twenty-nine half towers, and four overhanged bartizans, as well as numerous towers of various architectural forms.
