A military bunker structure located near Bergen, Norway, designated with the alphanumeric identifier 'Ma Fl Bat Blaaman - Ma Fl A 4/802'. The naming convention suggests a possible connection to German naval fortifications (Marinefestungsbatterie) from the World War II era, consistent with the extensive Atlantic Wall fortifications built in occupied Norway. However, without specific archival or historical records confirming its construction, purpose, or current state, detailed historical and technical information remains unverified.
The site's precise function, armament, and period of use cannot be confirmed from available data.
