La Sagrada Familia, the Roman Catholic church that Antoni Gaudí started building in the 1880s and . . . might be finished someday? Maybe? When Gaudí died in 1926, it was less than a quarter built, and now they’re guessing that it’ll be finished 100 years after that. The government isn’t paying for this, so the $$ you pay to visit are what’s funding the completion! Pretty cool!
