Since the early Middle Ages there was a earth – wood stronghold in Rega river bend, mentioned in 1180. The market settlement next to it was so significant that in 1277 it received Lubeck municipal privilege. Permission for the construction of the walls Trzebiatów obtained from prince Bogusław IV in 1299. They were built until the middle of the 14th century, and in the fifteenth century were modernized, because thanks to the convenient location at the river the town developed as an important trade center, from 1365 belonging to the Hansa. Since 1784 medieval fortifications began to be successively stripped to the building materials.
Trzebiatów walls were about 2,500 meters long. It covered an area similar to the oval in plan, pressed in a bend of the river. Wall was reinforced with numerous towers, initially half towers, i.e. open from the town side. It were slightly higher than the crown of the wall and spaced at fairly regular intervals within the effective range of the crossbow (i.e. about 30 meters). The key fragment of the circuit, namely the southern corner of the town, was protected by a full cylindrical tower called Powder Tower (Kaszana).
The town had four gates: Kołobrzeska, Gryficka, Sailors and Bath Gate. Gryficka and Kołobrzeska were the oldest and most important ones, they had also foregates since the end of the Middle Ages. The Bath Gate has been mentioned since the mid-16th century, whereas Sailors Gate only in 1784.
From the old fortifications, has survived a defensive wall of 1.6 km length, but reduced in height, the Powder Tower, also known as Groats Tower and the remnant of the moat from the west side. The name of the Groats Tower is related to the legend that in the fifteenth century one of the guards guarding the walls, drove from the tower a bowl of hot groats. It fell on the head of one of the Gryficzans preparing for assault on Trzebiatów. This accident was to save the town from a sneaky attack.
