Parc du Cinquantenaire Brussels

Parc du Cinquantenaire was built during Léopold II's reign. It's best known for its cluster of museums – art, history, military and motor vehicles – which house an incredible 350,000 artefacts. The Royal Art and History Museums in the southern wing of the Cinquantenaire buildings are chock-a-block with antiquities. Autoworld, in the northern building, has a huge collection of vintage cars. There is also the massive Arcade du Cinquantenaire, a triumphal arch built in 1880 to celebrate 50 years of Belgian independence.
