From the 7th to the 5th centuries BC on the nearby lake there was a wood and earth stronghold of the Lusatian culture. In the 10th century, at the crossroads of trade routes, a Pomeranian hillfort and a fishing village were located, handed over in 1261 by the Templars to the Margrave of Brandenburg. The defensive walls of Myślibórz were erected in the second half of the 13th century, during the intensive development of the town, which in 1298-1537 was the capital of the Neumark and, consequently, the economic center of the region. For the first half of the fifteenth century, the town was in the hands of the Teutonic Knights. This led to the burning of the town by the Hussites in 1433, and in 1473 to capture and destruction by the West Pomeranian prince, Bogusław X. The next destruction of the town, and thus damages to the fortifications, took place in sixteenth century because of fires and in the seventeenth century during the Thirty Years War. The fire of 1539, which consumed almost all buildings, was particularly severe. After the removal of the damage, a decision was made to rebuild also the town’s fortifications, but already on the changed plan. Saved fragments of defensive walls were adapted to the new town. The ravages and development of firearms have led to a gradual decline of the importance of the Myśliborz fortifications.
The defensive walls are made of granite, field stones and in a lesser extent, of brick. Their length was about 1900 meters. Within the walls there were three gates and 49 towers, mainly half towers, spaced 24 – 30 meters. To the town was led from the west side Mill Gate, also called Kostrzyń Gate, from the north by Pyrzycka Gate and from the east by Nowogródzka Gate, also known as the Gorzów Gate. Initially, they had the form of prisms, later they were raised and topped with facades fragmented with blendes. The Mill Gate had a foregate consisting of a neck, ending with two cylindrical towers, connected by a wall with a centrally located passage. The walls were reinforced with a earth ramparts and a double ring of moats.
To this day, the Nowogródzka Gate, the Pyrzycka Gate and the Powder Tower have been preserved. You can also find numerous fragments of the defensive wall, also with half towers.
