During the second world war, more than 20 war airfields were built in Sweden and one of these was on Brattforsheden about fifty kilometres north of Karlstad. The airport was named War Airfield 16 and both stalls and hangars were camouflaged so that it would resemble ordinary houses and barns. Smaller anti-aircraft systems were camouflaged as the nature they were surrounded by. Around the airfield there were both rifles, shelters and anti-aircraft positions. After the war, the airfield remained in service until the eighties when the land returned to its owners. Since 2003, Brattforsheden has been a cultural reserve, but the airport is still used by sports pilots.

Current status: preserved with museum (2011).

Location: 59º 36' 51,48 N 13º 55' 55,2 E

My comment:

In addition to aircraft shows of veteran aircraft, there are also old military vehicles, anti-aircraft guns and machine guns in the area.
