The Basel City Walls are a former complex of walls in the central part of the Swiss city of Basel. The first city wall was completed around 1080 under bishop Burkhard von Fenis. A newer wall was constructed around 1230, which is known as the Inner Wall. In 1362 the construction of a larger wall complex began due to the city's expansion; it was completed in 1398, and is known as the Outer Wall. In 1859 the city's executive decided to raze wall and gates to the ground.
