The defensive walls of Prabuty were erected in the 14th century, probably soon after the granting of municipal privilege, which took place between 1305 and 1321. Since the 18th century the neglected fortifications were gradually dismantled.
Surrounded by fortifications, the town received a regular, oval-like outline, adapted to the form of the area, bounded from the west by Lake Liwieniec. In the middle of them a square market was placed, located slightly east of the town’s main axis and enclosed by two parallel streets converging at the entrance gate. In the north-west corner a bishop’s castle was incorporated into the fortifications. Right next to the defensive walls there was also a parish church with a massive tower at the chancel, and the line of fortifications itself was strengthened by numerous four-sided towers, probably initially open from the town side.
Three gates led to the city: Kwidzyń Gate, also known as Hospital Gate, High Gate and Royal Gate. There was also a wicket gate in the western part of the wall, sometimes called the Pot Gate. The Kwidzyń Gate is brick and is based on a square plan with a side of about 8,5 meters. Its facades are decorated with plastered blendes. Below is a pointed arch with a groin vaulted crossing.
To this day, the only survivable element of the medieval fortifications of Prabuty is the Kwidzyń Gate and the eastern part of the gothic wall adjoining it. In the gatehouse there is a room with an exhibition of souvenirs, paintings, prints and decorations related to the history of Prabuty and the second room with collections and model of the former bishop’s castle.
