The fortification system was sold to Copenhagen municipality in 1869 and largely dismantled the year after. Evidence of the walls can be found in the street names outlining the central part of the city. From Kastellet at the northeast point of the district runs "Øster Voldgade" ("Eastern Wall Street") to the southwest. The street changes names near Nørreport Train Station and continues as "Nørre Voldgade" ("Northern Wall Street"). "Vester Voldgade" ("Western Wall Street") starts at Ørsteds Park and runs southeast until it reaches the water of Copenhagen Harbour ("Københavns Havn"). The fortification system continues on the other side of the water in the Christianshavn city district.
