The Architecture of Argentina can be said to start at the beginning of the Spanish colonisation, though it was in the 18th century that the cities of the country reached their splendour. Cities like Cordoba, Salta, Mendoza, and also Buenos Aires conserved most their historical Spanish colonial architecture in spite of their urban growth.
The simplicity of the Rioplatense baroque style can be clearly appreciated in Buenos Aires, in the works of Italian architects such as Andre Blanqui and Antonio Masella, in the churches of San Ignacio, Nuestra Se˝ora del Pilar, the Cathedral and the Cabildo.
Italian and French influences increased after the wars for independence at the beginning of the 19th century, though the academic style persisted until the first decades of the 20th century. Attempts at renovation took place during the second half of the 19th century and beginning of the 20th, when the European tendencies penetrated into the country, reflected in numerous important buildings of Buenos Aires, such as the Santa Felicitam Church by Ernesto Bunge; the Central Post Office and Palace of Justice, by Norbert Maillart; and the National Congress and the Colon Opera House, by Vittorio Meano.
A number of young Italian architects, including Virginio Colombo, Francisco Gianotti and Mario Palanti who designed the Italian pavilion for the Exposicion Internacional del Centenario (1910), went on to establish successful careers in Buenos Aires working in a number of styles, including Art Nouveau. Their buildings were some of the most important of the 20th century in Buenos Aires and those that remain continue to play a significant role in defining the city's architectural landscape.
The architecture of the second half of the 20th century continued adapting French neoclassical architecture, such as the headquarters of the National Bank of Argentina and the NH Gran Hotel Provincial, built by Alejandro Bustillo, and the Museo de Arte Hispano Fern├índez Blanco, by Martin Noel.
However, after the early 1930s, the influence of Rationalist architecture and of Le Corbusier became dominant among local architects, among whom Alberto Prebisch and Amancio Williams stand out in this new vein. The construction of skyscrapers proliferated in Buenos Aires after 1950, though a new generation started rejecting their "brutality," and tried to find an architectonic identity.
This search for identity is reflected in the Banco de Londres building finished in 1967 by Clorindo Testa with Diego Peralta Ramos, Alfredo Agostini, and Santiago Sanchez . In the following decades, the new generations of architects incorporate, as always, European vanguardist styles, and new techniques.
Since the latter part of the 20th century, Argentine architects have become more prominent in the design of prime real estate projects in the country, such as the Le Parc tower and Torre Aqualina, by Mario Roberto alvarez, and the Torre Fortabat by Sanchez El├a, as well as around the world, most notably the Norwest Center and the Petronas Towers, both by Cesar Pelli.
