A former military training ground, in 1880 Parc du Cinquantenaire hosted the celebrations commemorating the fiftieth anniversary of Belgium’s independence. In this connection, large structures were built in the park to host fairs and exhibitions. The imposing arcades, desired by King Léopold II, crowned the project in 1905. In addition to several grand museums, the park possesses an extraordinary, but often little known, architectural heritage. The scandalous Temple of Human Passions, the old panorama of Cairo, now transformed into a mosque, or the medieval tower designed by architect Henri Beyaert, are just some of the many examples. This walking tour is an opportunity to learn about the history of the park as well as its unexpected riches.
