The largest museum in Skopje is the Museum of the Republic of North Macedonia which details the history of the country. Its icons and lapidary collections are particularly rich. The Macedonian Archeological Museum, opened in 2014, keeps some of the best archeological finds in North Macedonia, dating from Prehistory to the Ottoman period. The National Gallery of Macedonia exhibits paintings dating from the 14th to the 20th century in two former Turkish baths of the Old Bazaar. The Contemporary Art Museum was built after the 1963 earthquake thanks to international assistance. Its collections include Macedonian and foreign art, with works by Fernand Léger, André Masson, Pablo Picasso, Hans Hartung, Victor Vasarely, Alexander Calder, Pierre Soulages, Alberto Burri and Christo.
