Palma de Mallorca Airport occupies an area of 6.3 km2 (2.4 sq mi). Due to rapid growth of passenger numbers, additional infrastructure was added to the two terminals A (1965) and B (1972). This main terminal was designed by local architect Pere Nicolau Bonet and was officially opened on 12 April 1997. The airport now consists of four modules: Module A (the former Terminal A Building), Module B (the former Terminal B Building), Module C and Module D (the last two were completely new sets of buildings and gates that opened along with the new central terminal and check in area in 1997). The airport can handle 25 million passengers per year, with a capacity to dispatch 12,000 passengers per hour.
