Copenhagen hosts the major New Year's Eve fireworks display associated with Tivoli Gardens. The historic amusement park in the Danish capital is a prominent setting for seasonal celebrations, including a fireworks festival around the New Year.
Tivoli Gardens opened in 1843 and occupies a central location in Copenhagen. Its combination of rides, gardens, restaurants, concerts, and seasonal decorations makes it a major visitor attraction rather than merely a fireworks venue.
The fireworks tradition is connected with the park's winter and New Year's programming, though dates and operating details can change. Copenhagen also has many independent public and private fireworks displays, so Tivoli's show should not be treated as the city's only celebration.
A useful distinction is between the city and the attraction: Copenhagen is the answer to the location question, while Tivoli Gardens is the specific park. Aarhus, Odense, and Aalborg are also Danish cities, but they are not the city named by this landmark association.
