Sagrada Familia is one of the most visited buildings in the world. On this guided tour, you will explore the facades and interior of the basilica, where vaults reach nearly 70 metres. Designed with a Latin cross plan with five aisles, the cathedral is extremely rich in ornamentation and symbolism. You will witness the colours of the stained glass windows as you walk inside this holy church, and also visit the crypt of Antoni Gaudí, the architect who designed the basilica.
