This visitor center on the Cape Verde island of Fogo, designed by Lisbon-based Oto Arquitectos, took seven years to complete. It was inaugurated last April, was named cultural building of the year in Archdaily's Building of the Year 2015 awards, and was then promptly destroyed by a volcano. "It took us seven years after we won the completion and it lived seven months," one of the architects told Dezeen. "We think buildings are forever but nature is stronger." Volcanos, especially.
