The City Park Ice Rink is a public ice rink located in the City Park of the Hungarian capital Budapest, between the Heroes' Square and the Vajdahunyad Castle. Opened in 1870, it is the largest and one of the oldest ice rinks in Europe. In summer months the area is filled up with water to create a pond, which is primarily used for boating, but also hosted several special events, such as the snowball fight world record attempt in 2009 or the Art on Lake exhibition in 2011.
