La Sagrada Familia has to be one of the "must see" attractions in Barcelona. Although I enjoyed the houses (Casa Batlló and La Pedrera/Casa Mila) for their stunning architecture, the sheer scale of Gaudi's cathedral masterpiece is hard to appreciate until you visit (maybe the fact that it's not expected to be completed for quite a few more years gives some idea!). It's also incredibly light inside and quite unlike any other cathedral I've visited - modern or ancient. Unfortunately we couldn't travel to the top of the towers on the day we visited and parts of the church were closed for a service that was due to take place later in the day, but I'm really glad we made it out there. Definitely recommended. Don't forget to take a look at the exhibition in the vaults whilst you are there!
