During my stay in Barcelona, my bestie Michelle joined me for 10 lovely days, and we surely made every moment count. We ambled along La Rambla, drank cervezas and enjoyed tapas at many tapas bars, and giggled endlessly as we "learned to navigate" the Barcelona Metro (that's my nice way of saying we got on the wrong train more than once!).
But we took that Metro all over and saw some amazing sights. Our first big adventure was La Sagrada Familia. This is an absolutely, must-see, no question about it. As I think about all the different personalities of people I know, I can't imagine any of them not fully enjoying what might be considered Gaudi's most significant work. As with everything Gaudi, it's over-the-top, beyond strangely weird, brilliant, and this one includes the whole religious bent. The detail of the carvings, and the amount of work it took just to get people in place to carve them, is staggering.
We also visited Casa Batlló, which is considered one of Gaudí's masterpieces.
