I had heard about this very special Gaudi building - one just outside of Barcelona though very easy to get to by train from Plaza Espagna. The Gaudi Crypt is only one part of what there is to see in this village that was developed by the industrialist Guell to house the workers who worked in his textile factory, The little village is really interesting and you can spend a good 2-3 hours wandering around and looking at the cool building in the village. Really well worth it and a nice change from the bustle of Barcelona. An excellent example of the genius of Gaudi but other architects buildings to see in the village too. The audio tour very well worth it too!
