Stadsgraven is the canal which separates Christianshavn from the rest of Amager in Copenhagen, Denmark. It was originally a moat located in front of the Christianshavn Rampart as part of the city's Bastioned Ring Fortifications.Stadsgraven was created when Christianshavn was constructed in the shallow waters off Amager in the early 17th century. Apart from the main Stads canal, there is a parallel Inner Stadsgraven along its northern portion.
