Capitolio (El), Havana

Built in 1929 to house the island's Senate and House of Representatives, National Capitol Building and with a dome that dominates the Havana skyline, this building looks rather similar to the Congress on Capitol Hill in Washington DC. Inside there is a statue of La Republica, the biggest indoor bronze effigy in the world. There is also an enormous and historic gallery called the Salón de los Pasos Perdidos (The Hall of Lost Steps); a 25-carat diamond that marks the exact centre of the city; and the headquarters of the Cuban Natural History housing the country's largest natural history collection.
