Christianshavn and the sub district of Holmen, is a peninsula stretchingout north through the old fortifications - because of this it issurrounded by water, and only access is across the Knippelsbro bridge,and the dam to Amager. It is entirely located within Zone 1 of thecommon ticketing system of the Metro, trains and busses. It is only a pleasurable 10 minute walk from Strøget on Amagertorv, past the parliament, and over the Knippelsbro bridge, if you don't want to pay for public transit.
