Inauguration of the world's tallest church - Sagrada Familia in Barcelona

The inauguration ceremony of Sagrada Familia, the world's tallest church, was held in Barcelona, 144 years after the start of construction and 100 years after the death of architect Antoni Gaudí. Pope Francis consecrated the last tower installed, followed by a large-scale drone show. Although the opening ceremony has taken place, interior decoration work will continue until 2035.
