Pope Leo XIV has celebrated the Sagrada Familia Basilica as a masterpiece of "stones, colours and light" as he marked the centenary of the death of its architect, Antoni Gaudi, with a Mass under its soaring sandcastle spires.
Leo called Gaudi's unfinished temple, one of the world's most visited monuments, a "sign of unity and harmony for all of Spain," an ongoing building project like the lifelong journey all Christians make to find God.
"We are all the living stones of this edifice," Leo said from the altar of the basilica, with Spanish King Felipe VI and Queen Letizia sitting to his side and a hundreds-strong choir filling the soaring basilica with song.
