Sagrada Familia features 18 huge towers representing the 12 Apostles, the 4 Evangelists, the Virgin Mary and, the tallest one, Jesus Christ, which, upon the cathedral’s completion will have a huge cross mounted on top. The height of the church will be of 170 meters, one meter shorter than a neighboring hill, because Gaudi believed his creation shouldn’t be higher than God. It will have three facades, the Nativity to the East, the Glory to the South and the Passion to the West.
You might think the building process has already taken too long but at the start of the 20th century, specialist predicted the project would be completed in several hundred years. Thanks to technological progress we might live long enough to see it completed.
