The planned height of the Sagrada Família’s tallest tower is 172.5 meters.
That tower is the central Tower of Jesus Christ, the highest of the basilica’s planned eighteen spires. Gaudí designed its final height to remain below Barcelona’s Montjuïc hill, reflecting his belief that human construction should not surpass God’s creation.
The tower is topped by a large cross and is surrounded by four somewhat shorter towers representing the Evangelists. Other spires symbolize the Virgin Mary and the Twelve Apostles, creating a theological hierarchy in the building’s vertical design.
The figure is sometimes confused with earlier construction estimates or with the height of other towers. It refers specifically to the completed central tower, measured to its highest point. The Sagrada Família’s unusual silhouette comes from this deliberate arrangement of towers, façades and sculptural symbols rather than from a conventional single steeple.
