The Sagrada Familia was a highlight of being in Barcelona. I learned about it in more detail during one of my semesters of art history in college, but there’s still so much I didn’t know about it. The Basilica’s construction started in 1882, but won’t be completed until 2026. Though seeing a construction site isn’t always the prettiest, I’m so happy that we got to see it before its finished.
I would recommend pre-purchasing tickets to avoid a long line and even go for the audio tour. I would also take the recommendation we got–go in the afternoon or early evening to see how the stained glass windows change the colors inside the Basilica. There was plenty of room to walk around and explore when we went first thing in the morning, but at the same time there was a lot of people.
