This Roman Catholic basilica ranks among the most recognizable unfinished sacred buildings in the world. Construction began in 1882, and more than a century later, only nine of the planned 18 towers stand complete.

The facades display biblical scenes in detailed stone sculpture, while the interior rises on slender columns that branch like trees and filter colored light through the windows. The Sagrada Família merges Gothic traditions with organic forms and remains an active construction site, funded by admission fees and private donations.
