Frederiksberg (Danish pronunciation: [fʁeðʁeksˈpɛɐ̯ˀ]) is a part of the Capital Region of Denmark. It is formally an independent municipality, Frederiksberg Municipality, separate from Copenhagen Municipality, but both are a part of the City of Copenhagen. It occupies an area of less than 9 km2 and had a population of 103,192 in 2015.Frederiksberg is an enclave surrounded by Copenhagen Municipality. Some sources ambiguously refer to Frederiksberg as a quarter or neighbourhood of Copenhagen, being one of the four municipalities that constitute the City of Copenhagen (the other three being Copenhagen, Tårnby and Dragør). However, Frederiksberg has its own mayor and municipal council, and is fiercely independent.
Frederiksberg is an affluent area, characterised by its many green spaces such as the Frederiksberg Gardens, Søndermarken, and Hostrups Have. Some institutions and locations that are widely considered to be part of Copenhagen are actually located in Frederiksberg. For example, Copenhagen Zoo as well as several stations of the Copenhagen Metro (the stations Forum, Frederiksberg, Fasanvej, Lindevang, Flintholm, Axel Møllers Have, and Frederiksberg Allé) are located in Frederiksberg. The Copenhagen S-train system also has several stations in Frederiksberg, including Peter Bangs Vej station and Flintholm station.
