King Léopold II did not content himself with simply doubling the size of the estate around Château de Laeken. Until the end of his life, he endeavoured to acquire a large number of bordering properties: Belvédère, Stuyvenberg and several estates on the Heysel plateau. He also donated land to the nation for the development of a huge public park, the Royal Park of Laeken. Starting on the Heysel plateau, this walking tour will provide a better understanding of the true extent of the urban parks planned by the king. You will also learn about the various transformations that this heritage underwent during the two great universal exhibitions of 1935 and 1958, which resulted in further extensions and the creation of Osseghem Park.
