La Sagrada Familia
Location: Barcelona, Spain
Architect: Antonio Gaudí
Year Completed: Under Construction
Under construction since 1882, this monumental church designed by Antonio Gaudí has an expected completion date of 2026. With most of its design dictated by Biblical imagery, such as the 18 spires which are supposed to represent the Twelve Apostles, the Virgin Mary, the Four Evangilists, and Jesus Christ, almost every square-inch of the cathedral has some kind of higher meaning. Even without analyzing the Biblical allusions in the design, it is undeniable that Gaudí's cathedral is unlike anything else in the world.
