text:  I'm staying in Barcelona for this next story that's been getting a big response from you. And I'm going to start with the comments that you've been leaving on our Facebook page. Jim says, it's going to be weird when it's complete. It's never quite there-ness has almost become part of its charm. Petra in Germany said, it's breathtaking when you're there. Panji in Nigeria wrote, this is incredible. And Matty commented to say, it's the most beautiful church in the world.
