When Gaudi went for his weekly confession on June 7th 1926, he got accidentally hit by a tram and fell to the floor.
As a young man, Antoni Gaudi was very well kept. He used to wear nice jackets and boasted blue eyes and blonde hair, which he probably got from his french grand-grand-grand parents, whom are thought to be named the "Gaudin" family.
It seems that Gaudi didn't take care much about his appearance as an old man, that's why nobody recognized him on the day of that accident.
They thought he was a beggar and left him there for nearly two days. When he got taken to the hospital, he did not have any ID on him and when someone finally got it, his health had deteriorated too much for him to be saved.
Gaudi was very religious. He had been working for 43 years on the Sagrada Familia at the time of his death. Construction of the "cathedral of the poor" is still ongoing. Definitely worth a visit if you haven't been there yet !
