What is "nadderud"

Nadderud is a district in eastern Bærum, Norway. It was formerly farmland under one of Bærum's larger farms, named Nadderud, but since the 1950s it has been built up with housing, several schools and sporting facilities. The best known facility, which has made the name Nadderud nationally known, is the stadium Nadderud stadion. Parts of the district Nadderud have been absorbed by the growing suburban centre Bekkestua.
