Vestvolden, meaning 'the Western Rampart,' is Denmark's largest protected historical monument, stretching 14 kilometers from Avedøre to Utterslev Mose. Constructed between 1888 and 1892 by up to 2,000 workers in one of Denmark's greatest construction projects, this massive earthwork defense system remained in military use until 1920. Today, it is accessible to the public and serves as a vital green and recreational area in greater Copenhagen, combining historical significance with ecological importance. In Rødovre, visitors can experience 'Den historiske vold'—a cleared section revealing the original structures—while accessing guided tours, educational programs, and seasonal festivals celebrating Copenhagen's military heritage.
