Its large size, central location, and affiliation with the city hall makes it a popular venue for a variety of events, celebrations and demonstrations.
H. C. Andersens Boulevard, Copenhagen's most heavily congested street, and Vester Voldgade pass the square on either side of the city hall.
The four-winged, two-storey building was built in red brick to a design which was inspired by Italian Renaissance architecture.
The square was redesigned in 1995 and 1996 by KHR Architects, on the occasion of Copenhagen being the European Capital of Culture.
The intersecting street leading from Vesterbrogade to Strøget was removed, uniting the two sides of the square.
