Antoni Gaudi

Antoni Gaudi's Sagrada Familia in Barcelona, begun in 1882, remains under construction 100+ years after his 1926 death - and is now expected to be completed in 2026, funded entirely by tourist admission fees of 30 euros per person. UNESCO listed 7 of his works as World Heritage Sites, and the Catholic Church opened his beatification process in 2000, recognizing his devout life.
