Bestumkilen

Bestumkilen is a bay in Lysakerfjorden in the inner Oslofjord area of Norway.

Located west of the Bygdøy peninsula and east of Vækerø, it is bordered by the islet Killingen in the southwest and the mouth of the river Hoffselva at Sjølyst in the northeast.

[1] This stems from older times, when Bygdøy was an island, named Ladegaardsøen.

Bygdøy later became a peninsula due to post-glacial rebound, separating Bestumkilen from Frognerkilen.

[2] Propositions to reconnect Bestumkilen and Frognerkilen through a canal were made in 1928 and 1937, but not carried out.
