La Sagrada Familia
We got on the Hop on-Hop Off tour bus from Plaza Catalunya to get to La Sagrada Familia (no. 5 on TripAdvisor's recent Traveler's Choice list of Top 25 Landmarks of the World!)
Even if you see all the pictures, nothing compares to standing in front of Antoni Gaudi's masterpiece (still incomplete...decades later)
We stepped off the bus and our mouths were just hanging open the whole time.
