he City Hall Square (Danish: Rådhuspladsen) is a public square in the centre of Copenhagen, Denmark, located in front of the Copenhagen City Hall. Due to its large size, its central location and its affiliation with the city hall, it is a popular venue for a variety of events, celebrations and demonstrations. It is often used as a central datum for measuring distances from Copenhagen.The City Hall Square is located at the south-western end of the pedestrian street Strøget which connects it to Kongens Nytorv, the other large square of the city centre, passing Gammeltorv/Nytorv and Amagertorv along the way. Opposite Strøget, Vesterbrogade extends into the Vesterbro district and later crosses the border to Frederiksberg. H. C. Andersens Boulevard, Copenhagen's most heavily congested street, and Vester Voldgade pass the square on either side of the city hall.When the fortifications were disbanded in the 1850s, it was decided to use the vacant land for an exhibition area which played host to first the Nordic Exhibition of 1872 and later the Nordic Exhibition of 1888
