Memento Park is an open-air museum in Budapest, Hungary, dedicated to monumental statues and sculpted plaques from Hungary's Communist period (1949–1989). There are statues of Lenin, Marx, and Engels, as well as several Hungarian Communist leaders. The park was designed by Hungarian architect Ákos Eleőd, who won the competition announced by the Budapest General Assembly in 1991. On public transport diagrams and other documents the park is usually shown as Memorial Park.
