Sinsen is a mixed residential and commercial area inGrünerløkka borough ofOslo,Norway. The westernmost part of Sinsen is part of the boroughNordre Aker.
TheSinsen Interchange, located on the border between the boroughs of Nordre Aker, Grünerløkka andBjerke, was the firstroundabout in Norway. It has since developed into a multi-lever intersection, with bothRing 3,National Road 4 and theSinsen Line of theOslo Tramway routes around.[1] "North of the Sinsen Interchange" is common expression in the Norwegian district debates, where inhabitants of Oslo are accused of being ignorant of the country north of the interchange. The expression cropped up inrevues during the 1960s, and is probably due to that Sinsen then was the end point for the main road leading into Oslo from the north.[2]
The area is served by theSinsen Line of theOslo Tramway.[3] TheOslo T-bane serves the neighborhood atSinsen Station,[4]while theGjøvik Line serves the area atGrefsen Station.[5]
The neighbourhood is named after the old farm Sinsen (NorseSinnsin, from*Sinnsvin). The first element is thegenitive ofsinn meaning "road", and the last element isvin meaning "meadow". The area was an important crossroads also in old times, where the road from the bottom ofOslofjord ramified into the road east toRomerike and north toMaridalen/Hadeland.
