Oslofjord
The Oslofjord (Norwegian: Oslofjorden, Urban East Norwegian: [ˈʊ̂ʂlʊˌfjuːɳ]; English: Oslo Fjord[1][2][3]) is an inlet in the south-east of Norway, stretching from an imaginary line between the Torbjørnskjær and Færder lighthouses and down to Langesund in the south to Oslo in the north. It is part of the Skagerrak strait, connecting the North Sea and the Kattegat sea area, which leads to the Baltic Sea. The Oslofjord is not a fjord in the geological sense — in Norwegian the term fjord can refer to a wide range of waterways.

The bay is divided into the inner (indre) and outer (ytre) Oslofjord, separated by the 17 km (11 mi) long by 1 km (0.62 mi) wide Drøbak Sound. The innermost part is known as the Bunnefjorden.
