City Hall Square (Danish: Rådhuspladsen, pronounced [ˈʁʌðhusˌpʰlæsn̩]) is a public square in the centre of Copenhagen, Denmark, located in front of the Copenhagen City Hall. Its large size, central location, and affiliation with the city hall makes it a popular venue for a variety of events, celebrations and demonstrations. It is often used as a central point for measuring distances from Copenhagen. City Hall Square is located at the southwestern 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. Apart from the City Hall, notable buildings around the square include Politikens Hus, the headquarters of national daily newspaper Politiken, and Industriens Hus, the headquarters of the DI.

The 2000 UEFA Cup Final Riots, also known as the Battle of Copenhagen, were a series of riots in City Hall Square, Copenhagen, Denmark between fans of English football team Arsenal and Turkish team Galatasaray around the 2000 UEFA Cup Final on 17 May 2000. Four people were stabbed in the scuffles, which also involved fans from other clubs and were viewed by the media as part of a retaliation for the killing of two Leeds United fans by Galatasaray supporters the month before. The events of the day started early in the morning when skirmishes broke out in a bar, which led to an Arsenal fan being stabbed. Later in the day, Galatasaray fans occupied City Hall Square before heading towards Arsenal fans in bars nearby. The Galatasaray fans were later attacked from behind by members of British hooligan firms seeking revenge for the Istanbul stabbings. The police had prior warning of potential trouble and deployed 2,000 officers to the area, yet they were unable to control the riot until they fired tear gas. This led to 19 injuries, including 4 stabbings, and 60 arrests with similar events occurring in England and Turkey in the aftermath of the riots. Football authorities condemned the riots and threatened to expel national football teams from European competition if such events happened again. The Danish police were also criticized for their mishandling of the riots.

Copenhagen City Hall (Danish: Københavns Rådhus) is the headquarters of the Copenhagen City Council as well as the Lord mayor of the Copenhagen Municipality, Denmark. The building is situated on City Hall Square in central Copenhagen.

Copenhagen Municipality (Danish: Københavns Kommune), also known in English as the Municipality of Copenhagen, located in the Capital Region of Denmark, is the largest of the four municipalities that constitute the City of Copenhagen (Byen København), the other three being Dragør, Frederiksberg, and Tårnby. The Municipality of Copenhagen constitutes the historical city centre and the majority of its landmarks. It is the most populous in the country with a population of 652,564 inhabitants (as of October 2022), and covers 86.4 square kilometres (33.4 sq mi) in area,. Copenhagen Municipality is located at the Zealand and Amager islands and totally surrounds Frederiksberg Municipality on all sides. The strait of Øresund lies to the east. The city of Copenhagen has grown far beyond the municipal boundaries from 1901, when Frederiksberg Municipality was made an enclave within Copenhagen Municipality. Frederiksberg has the largest population density of the municipalities of Denmark.The municipal seat of government is the Copenhagen City Hall (Danish: Københavns Rådhus), the headquarters of the Copenhagen City Council. The Lord Mayor of Copenhagen is Sophie Hæstorp Andersen, since 1 January 2022. The relationship between Copenhagen Municipality and the wider city of Copenhagen is one of an administrative unit within a significantly larger city, cf. the City of London or the City of Brussels. In the Middle Ages, Copenhagen was defined as the area enclosed within the city walls. The city centre lies in the area originally defined by the old ramparts, which are still referred to as the Fortification Ring (Fæstningsringen) and kept as a partial green band around it. In 1856 the ramparts were pulled down allowing for growth and expansion. In 1901 the city expanded to include Amager and Valby, while Frederiksberg became an enclave within the municipality. The Finger Plan in the second half of the 20th century led to expansion outside the municipal boundary along the commuter lines of the S-train and the Lokaltog rail lines going to i.e. Helsingør (The Coast Line (Kystbanen) northbound) and Stevns Municipality (East Line (from Køge southbound) along the Øresund. The Copenhagen-Ringsted Line makes Køge one of the railway hubs of Eastern Denmark. Road and rail construction is planned to relieve traffic congestion because the narrow 14.5–15.3-kilometre (9–9.5 mi) isthmus between Roskilde Fjord and Køge Bugt (Køge Bay) forms a bottleneck. Copenhagen Municipality was one of the three last Danish municipalities not belonging to a county, the others being Frederiksberg Municipality and Bornholm. On 1 January 2007, the municipality lost its county privileges and became part of the Capital Region of Denmark.

Palace Hotel is a residential hotel on the eastern side of City Hall Square in Copenhagen, Denmark. Influenced by the Art Nouveau style, the red brick building was designed by Anton Rosen and completed in 1910.

The Copenhagen Fire of 1728 was the largest fire in the history of Copenhagen, Denmark. It began on the evening of 20 October 1728 and continued to burn until the morning of 23 October. It destroyed approximately 28% of the city (measured by counting the number of destroyed lots from the cadastre) and left 20% of the population homeless. The reconstruction lasted until 1737. No less than 47% of the section of the city, which dates back to the Middle Ages, was completely lost, and along with the Copenhagen Fire of 1795, it is the main reason that few traces of medieval Copenhagen can be found in the modern city. Although the number of dead and wounded was relatively low compared to the extent of the fire, the cultural losses were huge. In addition to several private book collections, 35,000 texts including a large number of unique works were lost with the University of Copenhagen library, and at the observatory on top of Rundetårn, instruments and records made by Tycho Brahe and Ole Rømer were destroyed.

H. C. Andersens Boulevard is the most densely trafficked artery in central Copenhagen, Denmark. The 1.3 km long six-lane street passes City Hall Square on its way from Jarmers Plads, a junction just north of Vesterport station, to Lange Bridge which connects it to Amager Boulevard on Amager. From Jarmers Plads traffic continues along Gyldenløvesgade which on the far side of The Lakes splits into Aaboulevard and Rosenørns Allé. At the City Hall Square the boulevard meets Vesterbrogade, another very busy and importaint street. Major landmarks along the street include Copenhagen City Hall, Copenhagen Central Fire Station and the Ny Carlsberg Glyptotek.

Copenhagen ( KOH-pən-HAY-gən, -⁠HAH- or KOH-pən-hay-gən, -⁠hah-.; Danish: København [kʰøpm̩ˈhɑwˀn] (listen)) is the capital and most populous city of Denmark, with a population of around 1.4 million in the urban area, and more than 2 million in the wider Copenhagen metropolitan area. The city is on the islands of Zealand and Amager, separated from Malmö, Sweden, by the Øresund strait. The Øresund Bridge connects the two cities by rail and road. Originally a Viking fishing village established in the 10th century in the vicinity of what is now Gammel Strand, Copenhagen became the capital of Denmark in the early 15th century. Beginning in the 17th century, it consolidated its position as a regional centre of power with its institutions, defences, and armed forces. During the Renaissance the city served as the de facto capital of the Kalmar Union, being the seat of monarchy, governing the majority of the present day Nordic region in a personal union with Sweden and Norway ruled by the Danish monarch serving as the head of state. The city flourished as the cultural and economic centre of Scandinavia under the union for well over 120 years, starting in the 15th century up until the beginning of the 16th century when the union was dissolved with Sweden leaving the union through a rebellion. After a plague outbreak and fire in the 18th century, the city underwent a period of redevelopment. This included construction of the prestigious district of Frederiksstaden and founding of such cultural institutions as the Royal Theatre and the Royal Academy of Fine Arts. After further disasters in the early 19th century when Horatio Nelson attacked the Dano-Norwegian fleet and bombarded the city, rebuilding during the Danish Golden Age brought a Neoclassical look to Copenhagen's architecture. Later, following the Second World War, the Finger Plan fostered the development of housing and businesses along the five urban railway routes stretching out from the city centre. Since the turn of the 21st century, Copenhagen has seen strong urban and cultural development, facilitated by investment in its institutions and infrastructure. The city is the cultural, economic and governmental centre of Denmark; it is one of the major financial centres of Northern Europe with the Copenhagen Stock Exchange. Copenhagen's economy has seen rapid developments in the service sector, especially through initiatives in information technology, pharmaceuticals and clean technology. Since the completion of the Øresund Bridge, Copenhagen has become increasingly integrated with the Swedish province of Scania and its largest city, Malmö, forming the Øresund Region. With a number of bridges connecting the various districts, the cityscape is characterised by parks, promenades, and waterfronts. Copenhagen's landmarks such as Tivoli Gardens, The Little Mermaid statue, the Amalienborg and Christiansborg palaces, Rosenborg Castle, Frederik's Church, Børsen and many museums, restaurants and nightclubs are significant tourist attractions. Copenhagen is home to the University of Copenhagen, the Technical University of Denmark, Copenhagen Business School and the IT University of Copenhagen. The University of Copenhagen, founded in 1479, is the oldest university in Denmark. Copenhagen is home to the football clubs F.C. Copenhagen and Brøndby IF. The annual Copenhagen Marathon was established in 1980. Copenhagen is one of the most bicycle-friendly cities in the world. Movia is the public mass transit company serving all of eastern Denmark, except Bornholm. The Copenhagen Metro, launched in 2002, serves central Copenhagen. Additionally, the Copenhagen S-train, the Lokaltog (private railway), and the Coast Line network serve and connect central Copenhagen to outlying boroughs. Serving roughly 2.5 million passengers a month, Copenhagen Airport, Kastrup, is the busiest airport in the Nordic countries.
