Sluseholmen (literally “The Sluice Isle”) is an artificial peninsula in the South Harbour of Copenhagen, Denmark. It takes its name from Slusen, a lock immediately to the south, regulating water levels in the harbor. Previously the site of heavy industry and part of the Southern Docklands of Port of Copenhagen, Sluseholmen has, since the turn of the millennium, undergone massive redevelopment, transforming it into a mainly residential district known for its canals and maritime atmosphere. It is connected to Teglholmen by the Teglværk Bridge.
Sluseholmen used to be dominated by heavy industry, including a Ford car factory. As industry left the area, a plan was conceived to develop Sluseholmen into a canal district. This was the result of co-operation between Sjoerd Soeters, Arkitema, the Port of Copenhagen and the City of Copenhagen. Construction started in 2004, the first residents arrived in 2007, and by 2008 development of the new canal district had been completed.
Sluseholmen today is dominated by the Sluseholmen Canal District development of 1,150 apartments, located on artificial islands and separated by dug-out canals.
Next to the canal district at the end of a pier extending from the tip of the peninsula, stands the Metropolis, a residential high-rise development designed by the experimental British architectural firm Future Systems. Its design has been inspired by the control tower on Langebro.
In late 2011, the third Copenhagen Harbour Bath opened at Sluseholmen. It was designed by Kasper Danielsen Arkitekter.
