The Parc du Cinquantenaire or Jubelpark is a large public, urban park of 30 ha in the easternmost part of the European Quarter in Brussels, Belgium.
Most buildings of the U-shaped complex that dominate the park were commissioned by the Belgian Government under the patronage of King Leopold II for the 1880 National Exhibition commemorating the 50th anniversary of the Belgian Revolution. During successive exhibitions, more structures were added to the site. The centrepiece memorial arch, known as the Cinquantenaire Arch, was erected in 1905, replacing a previous temporary version of the arcade by Gédéon Bordiau.
