La Sagrada Familia
Carrer de Mallorca, 401, 08013 Barcelona, Spain
Antoni Gaudi was commissioned to oversee the building of La Sagrada Familia in 1883, and it has since been recognized as one of the most breathtaking architectural feats! Miraculously, construction has been ongoing for over 136 due to political tumult and financial issues, but the people of Barcelona refuse to cease construction until La Sagrada Familia is fully complete (it is expected to be completed by 2040 at the latest). There are numerous tour companies that offer detailed guides of the enchanting church, or you can explore the stunning structure on your own. Children will marvel at the ornate stained glass windows and massive spires that extend hundreds of feet into the sky!
