Frederiksberg, a separate municipality within the urban area of Copenhagen, lies to the west of Nørrebro and Indre By and north of Vesterbro. Its landmarks include Copenhagen Zoo founded in 1869 with over 250 species from all over the world and Frederiksberg Palace built as a summer residence by Frederick IV who was inspired by Italian architecture. Now a military academy, it overlooks the extensive landscaped Frederiksberg Gardens with its follies, waterfalls, lakes and decorative buildings. The wide tree-lined avenue of Frederiksberg Allé connecting Vesterbrogade with the Frederiksberg Gardens has long been associated with theatres and entertainment. While a number of the earlier theatres are now closed, the Betty Nansen Theatre and Aveny-T are still active.
