Petrópolis (Portuguese pronunciation: [ˌpeˈtɾɔpuʎiʃ]), also known as The Imperial City of Brazil, is a municipality in the state of Rio de Janeiro, at a distance of 68 km from the state capital.

Nestled among the forested hills of the Serra dos Órgãos, in the valley of the Quitandinha and Piabanha rivers, Petrópolis is a popular winter holiday spot. Besides the climate and surroundings, the main attraction is the former Summer Palace of the second Brazilian emperor, which is now the Imperial Museum, specializing in Imperial history and memorabilia.
