Madrid-Barajas opened in 1931 on a plain northeast of the Spanish capital, with scheduled services developing through the 1930s before the Civil War intervened. It grew into Spain's principal airport and the home of Iberia, expanding through the postwar tourism boom with new terminals and runways. By the 1990s Barajas had become the essential bridge between Europe and Latin America, a role rooted in language, history and Iberia's network. The airport handles more flights to Latin America than any other in Europe.
The transformative leap came in February 2006 with the opening of Terminal 4 and its satellite T4S, designed by Richard Rogers and Antonio Lamela beneath an undulating bamboo-lined roof punctured by rainbow-colored supports. The project, which won the Stirling Prize that year, came with two new runways that doubled the airfield to four and made Barajas one of Europe's highest-capacity airports.
In 2014 the airport was renamed Adolfo Suarez Madrid-Barajas in honor of Spain's first democratically elected prime minister after the Franco era. Today it is the hub of Iberia and Air Europa and the largest airport in Spain.
