Barcelona is pressing ahead with the major project to complete the tallest tower of the Sagrada Família—the Tower of Jesus Christ. This week, workers installed the fourth and final horizontal element of the cross that crowns the tower. The structure now closely matches Antoni Gaudí’s original vision: a cross shining by day and glowing at night, rising above the city.
Installing each of the four horizontal elements is no easy task. Each weighs nearly 13 tons and measures about four meters in length. The geometry is complex: the outer edges are square, while the inner edges are octagonal to fit perfectly with the central core. Once finished, the entire cross will reach 17 meters high—the equivalent of a five-story building—and span 13.5 meters. This will make it the highest point not just of the basilica, but of all Barcelona.
Architectural details
Gaudí envisioned the cross with a unique double-rotation geometry, an idea that appears in other parts of the basilica as well. The finish uses white glazed ceramics and glass—materials that reflect sunlight and withstand the elements. At night, spotlights mounted on the evangelist and apostle towers will illuminate the cross, giving the basilica a striking look after sunset.
Inside the cross, a sculpture of the Lamb of God (Agnus Dei) by Italian artist Andrea Mastrovito will be installed. This element will serve as the symbolic completion of Gaudí’s decades-long architectural vision. The sculpture will only be visible from certain angles, adding mystery and intrigue for visitors.
Technology and challenges
Each stage of the installation process demanded precision and teamwork. Modern cranes and unique fastening systems were used to prevent even the slightest misalignment. The work was carried out at great heights, where even a gentle breeze could pose a serious hazard. Engineers and architects repeatedly noted that such tasks are extremely rare even in global practice.
Special attention was given to materials. Ceramics and glass were chosen deliberately: not only are they durable, but they also allow the cross to gleam in the sunlight. At night, the lighting will create the effect of a floating symbol in the sky, which is sure to attract even more tourists and pilgrims.
Significance for the city
With the installation of the cross, the Sagrada Família firmly secures its status as Barcelona’s architectural icon. The Tower of Jesus Christ will become the highest point in the city, surpassing even the famous Montjuïc hill. For locals and visitors alike, this event is not just a construction milestone—it is a true cultural and historic moment.
The symbolism of the cross, along with its scale and intricate craftsmanship, commands respect even from the most discerning architectural connoisseurs. Once again, Barcelona proves its ability to impress and inspire, remaining true to its traditions while boldly embracing the most ambitious ideas.
