The fortifications of the city of Friborg were built in the Middle Ages, between the 13th and the 15th century. The topography of the city was an asset for the creation of Fribourg. Its steep cliffs in molasse and the meanders of the river Sarine constituted a natural barrier against the enemy and the invasions. It is therefore on the west side of the city that the fortifications were built and thus formed a protective enclosure of the city.
Over time, Fribourg experienced changes in its urban planning and thus disappeared some fortifications. Today, this group of defense constructions forms the most important ensemble of medieval military architecture in Switzerland. Take the opportunity to discover this medieval heritage. Open from 9am to 7pm, the fortifications are accessible during the summer season for an individual visit or with a guide. The fortifications of the city of Fribourg consist of gates and towers connected in part by sections of ramparts (original enclosure).
