Gaudi died in the late 1920s, and they only finished construction on a tiny fraction of his original vision for the church. Something like 4 out of the planned 18 towers.
Unfortunately, for Gaudi, he met the ill-fate of being run over by a tram. Dan heard me say over and over the whole trip...how the heck do you get run over by a tram?
Then, while we were in Zurich, which has about a bajillion trams, I was carelessly NOT paying attention while taking photographs of the main train station. Dan crossed ahead, while I hung back to let one tram pass by before stepping out into the street, only to turn at the sound of the "I´m going to run you over if you don´t get the hell out of my way," bell from the second tram, coming the other way.
Yeah, that´s how you get run over by a tram.
Above is an example of some of the intricate work on the facade of the original church. Apparently, Gaudi was a deeply religious man, so working on Sagrada Familia was like a calling for him.
