 Today Frederiksberg consists almost entirely of 3- to 5-story residential houses, large single-family homes, and large parks; only a few small areas with light industry remain.Frederiksberg, which lies west of central Copenhagen, is completely surrounded by boroughs forming part of the city of Copenhagen – the result of an expansion of the Copenhagen Municipality's boundary in 1901, which nevertheless did not include Frederiksberg in the list of municipalities to be incorporated in the enlarged area.Frederiksberg is thus effectively a municipal island within the country's capital – a unique phenomenon in present-day Europe.
