The Capitolio is located on the Paseo de 
				Martí, extending from the Parque Central to the Parque de la 
				Fraternidad.
					
The Capitolio, one of the most 
					emblematic buildings of the capital, was used as the Cuban 
					Congress, but in 1959 it was abolished and disbanded, losing 
					its symbolic authority. Since that time, it houses the 
					Academia de Ciencias de Cuba (Academy of Sciences of Cuba) 
					and the Ministerio de Ciencia Tecnología y Medio Ambiente 
					(Ministry of Science Technology and Environment).
The Capitolio played an important 
					role in the recent history of Cuba, since its halls 
					witnessed the enactment of the Constitution by the 
					Constituent Assembly in 1940. In 2010 it was closed to 
					public for extensive restoration. The building is still 
					under restoration and it is estimated that about 80% of the 
					restoration process has been completed. Thus, except the 
					south wing, the building is opened to public, but only 
					guided tours are allowed. 
					
HISTORY
In the first decade of the 20th 
					century, the government agreed on building a presidential 
					palace. The President José Miguel Gómez (1909-1913) issued a 
					decree to form a commission that would determine the terms 
					and conditions of the international contest to select the 
					design of the presidential palace. The train station of 
					Villanueva was chosen as the place for building of the 
					presidential palace, as the old train station had 
					deteriorated after the appearance of the tram and the 
					omnibus. In 1914 the construction was entrusted to the Cuban 
					architects Félix Cabarrocas and Mario Romañach.
Felix Cabarrocas prepared his 
					project by taking the architecture of French Renaissance 
					style as a paradigm. He made a change in the project by 
					congregating the Senate and the House of the Representatives 
					in the same building. While he dedicated himself to the 
					outer of the building, Romañach focused on the interior. The 
					construction process continued without interruption until 
					1919, when Mario García Menocal, the third President of 
					Cuba, suspended the work as a result of the increase in the 
					cost, requisitioned by the contractors because of the new 
					additions and modifications. In fact, almost half of what 
					had been built during the five years, were lost by the new 
					modifications and adaptations that made the work more 
					expensive. Although the building process resumed one year 
					later, it was halted by Alfredo Zayas, the fourth President 
					of Cuba, again due to the serious economic crisis that 
					loomed large on the island in 1921. The construction area 
					was leased to a private company that had installed the 
					Havana Park. In the course of time all the instruments, used 
					by the contractors disappeared and the derelict building 
					deteriorated.
In 1925 Gerardo Machado, the fifth 
					President of Cuba, appointed Carlos Miguel de Céspedes as 
					the Secretary of Public Works and entrusted him with putting 
					the master plan of Havana to practice. Carlos Miguel de 
					Céspedes was an energetic person that had succeeded in the 
					construction of some important roads, parks and buildings, 
					such as the highway (Carretera Central), Avenida del Puerto, 
					Paseo del Prado, Hotel Nacional, Plaza de la Fraternidad, 
					Central Library and some buildings of the University of 
					Havana. He was called as El Dinamico due to his great effort 
					in beautification of Havana during his short secretarial 
					duty (1925-1929). Carlos Miguel de Céspedes commissioned 
					Félix Cabarrocas and another Cuban architect Evelio Govantes 
					to continue with the construction of the Palace of 
					Congresses. The North American Purdy and Henderson Company 
					that had carried out also the construction of the Lonja de 
					Comercio, the Centro Asturiano (National Museum of Fine 
					Arts), the Centro Gallego (the building that hosts Gran 
					Teatro today), the steps of the University of Havana, 
					obtained the tender and the construction restarted in 1926.
The building plot occupied more than 
					43.000 m2. The manpower, consisting of around 8.000 men, was 
					obtained by the Spaniards (in great majority), Cubans and by 
					other nationalities that arrived the island from the nearby 
					countries with the hope to find a job. At that time there 
					was not enough qualified person that would undertake a 
					stonework of such magnitude, and any equipment to be used in 
					molding the stones that have the hardness similar to marble. 
					The stonemasons used diamond blades in cutting the stones 
					into square shape with minimum roughness meticulously. 
					Compressed air, pumice stone (as abrasive) and limestone (as 
					dent filler) are used to smooth the exposed surfaces. The 
					stone blocks, many of which weighed up to nine tons, were 
					transferred from the quarries to the construction area by 
					rail. A powerful crane, with a capacity for 15 tons, was in 
					charge of unloading the stone blocks.
The construction period lasted for 3 
					years 3 months and 20 days and costed to the state budget about 17 million of 
					American dollars. More than 5.000 workers were employed, and 
					5 million bricks, 150.000 bags of cement, 1 million meters 
					of wood, 38.000 m3 of sand, 3.500 tons of steel, 2.000 tons 
					of rebar and 40.000 m2 of stone were used. 8.000 m2 of 
					floors, including the Salón de Pasos Perdidos and the 
					Senate, and 2.000 m2 of the stairs were covered 
					with marbles, brought from Italy.
El Capitolio was inaugurated in 1929 
					amid huge celebrations.
