"La Sagrada Família," a dramatic, imposing cathedral designed by Spanish architect Antoni Guadí, is easily Spain's most recognizable landmark, and it isn't even finished yet. Construction began on the church 133 years ago, in 1882, and it continues to this day.
Work crews recently began the final phase of construction, meaning the church will soon be complete after more than a century of work. It's expected to be done in 2026.
Tourists have come from across the world to see the progress of construction on the cathedral, which has soaring ceilings, intricate facades, and bright stained-glass windows. More than three million people visit the temple each year, according to National Geographic.
The tallest tower will eventually be 564 feet high, making it the tallest religious structure in Europe.
