Sagrada Familia is one of the most beautiful churches I’ve ever visited. The admission price is definitely worth it to wander around inside. Just look at the ceiling, columns and stained glass windows. I just love all the shapes and colours on display.
I recommend going to the top of the Sagrada Familia for the impressive views of Barcelona too.
If you don’t buy a ticket for the inside of the Sagrada Familia, it’s still worth visiting the facade from a distance – just look at the detail!
