Sagrada Família · Eixample
The most visited building in Spain has been under construction for over 140 years — and was started by a man who knew he'd never see it finished
Antoni Gaudí took over the Sagrada Família in 1883 and immediately knew the project would outlast him. He spent the last 16 years of his life living in the crypt, working exclusively on it. When he was struck by a tram in 1926, he was so simply dressed that passersby assumed he was a beggar. He died three days later. Construction is expected to finish in 2026 — 144 years after it began.
