WW II Mine fields in the Oslo fjord
- British air-dropped mining of
the inlets to Oslo
- Established in May 1940,
September 1941 and November 1941 in the inner part of the fjord
- Established between
September 1944 and April 1945 in the outer parts
- “Cleared” mid 90s using
Oksøy class
- 30+ new objects found a few
years ago
- Several new objects found last
year
