After braving the towers of La Sagrada Familia, it was on to the spiral staircase that was the only way down. It’s a good thing I’m not claustrophobic. The staircase looked like the inside of a seashell, one person wide and spiraling down around an opening about a foot wide. Looking straight down, it’s impossible to tell how many floors up you are. It didn’t help that I didn’t pass a single person on the way down (which was enough to make me wonder if I was actually going the right direction). Crazy stuff. My knees were pretty shaky after climbing all the way back down.
