I can’t imagine any edifice on the planet that might hold a candle to this endlessly spectacular work of art. Antoni Gaudi began his massive project at only 31 years old, and worked on it for 43 years — from 1883 until his accidental death in 1926 when he was hit by a tram. An incredibly massive project imagined and brought to a life by a genius who viewed possibility as few others could, Gaudi realized that he might not live until its completion. As a safety measure before his death. he left a model showing the main shapes of the building that would later be constructed. Anticipated completion date is 2026, and I can’t wait to go back.
