Teglholmen (English: The Tiles Islet) is a peninsula in the South Harbour of Copenhagen, Denmark, located between Sluseholmen and Enghave Brygge. The former dockland area used to house heavy industry. While some industry activities remain in the area, but since most industry left the area, starting in the 1970s, it has undergone massive redevelopment, though some industrial activities remain, most notably MAN B&W Diesel's motor development plant. Today the area houses both a considerable number of Danish and regional headquarters of multinational companies and residential developments. Teglholmen is home to Aalborg University's AAU Cph Campus as well as TV 2's activities in Copenhagen.
Teglholmen takes its name from a tile works which established in the area in 1871, for many years supplying particularly Vesterbro with tiles. Around World War I, the tile works closed and the extensive clay pit was turned into a new harbour basin by connecting it to the main harbour, forming what is today known as Teglværkshavnen, separating Teglholmen from Sluseholmen. The next generation of companies to establish in the area were shipyards, foundries and a car assembly plant.
In the 1970s, the industrial activities in the Teglholmen area started to close and from the end of the 1990s, a number of multinational companies started to establish Danish or Regional headquarters at Teglværkshavnen. From the middle of the 2000s, Teglholmen also started to attract residential developments. In 2006, Odense-based TV2 collected its Copenhagen activities in a new media house at Teglholmen.
The residential areas at Teglholmen are created as a continuation of the canal district at Sluseholmen. Companies located at Teglholmen include Nokia, Philips, Ericsson and TV2 .
