Tivoli Gardens (or simply Tivoli) is an amusement park and pleasure garden in Copenhagen, Denmark. The park opened on 15 August 1843 and is the second-oldest operating amusement park in the world. Tivoli's founder, Georg Carstensen (b. 1812 – d. 1857), obtained a five-year charter to create Tivoli by telling King Christian VIII that "when the people are amusing themselves, they do not think about politics". The monarch granted Carstensen use of roughly 15 acres (61,000 m²) of the fortified glacis outside Vesterport (the West Gate) for an annual rent. (wikipedia.org)
