The northern suburbs of Stockholm, Norrort [ˈnɔrˈuʈ], consist of several municipalities, separate from Stockholm: Danderyd, Täby, Vallentuna, Sollentuna, Upplands-Väsby, Upplands-Bro and Järfälla. To the west they border Västerort (the western suburbs) and Western Uppland; to the north is Sigtuna, and to the east Roslagen and Stockholm archipelago.
During the Viking Age and Middle Ages, the area was known as Attundaland, an entity surviving only with the fire brigade Brandkåren Attunda and the courthouse Attunda Tingsrätt.
During the 20th century, the area between Sigtuna and Stockholm transformed from farms to suburbs. Helenelund and Danderyd are affluent garden cities.
