City walls in Lubin - built in the 14th century possibly in the place of old ramparts reinforced with a palisade, which surrounded the city and served a defensive function. Extensive construction of the walls took place in the years 1348-1358[1] - just before and during the civil war between the sons of Bolesław the Generous, when Lubin was the residence of Duke Louis I of Brzeg. The construction of the walls was completed in the second half of the 14th century when they were incorporated into the city's defensive system.
