Although The Sagrada Familia is far from complete, it is definitely worth the visit. The church is extremely rich in ornamentation and symbolism, and has vaults that reach 230 feet. You can even visit the crypt where Gaudi is buried. A museum tells the story of this great architect and church history. To get to the top of the towers, visitors must take the elevator. From the top of the tower, you will have one of the most beautiful views over Barcelona.
