Memento Park is an open-air museum in Budapest, dedicated to monumental statues 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.
Memento Park is divided into two sections: Statue Park, officially named “A Sentence About Tyranny” Park after a poem of the same name by Gyula Ilyés, and Witness Square (also called 'Neverwas Square'). Statue Park houses 42 of the statues that were removed from Budapest after the fall of communism. Witness Square holds a replica of Stalin's Boots which became a symbol of the Hungarian Revolution of 1956 after the statue of Stalin was pulled down from its pedestal in 1956.References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
