Sagrada Familia is situated in Barcelona. It was designed by Antonio Gaudí and it was buit in 1882, but now it's still in works. Some important people are buried there. The temple, when finished, will have 18 towers. This cathedral is very important, but for many years it's been in construction.
In my opinion, Sagrada Familia is very famous in Barcelona. It's one of the best places to visit. If you like cultural places, you should go there! I recommend it to you!
