Sagrada Familia: World's Longest Construction Project Finally Ending!

Finally, after 144 years of labor and political upheaval, the Sagrada Familia is entering its final stage. For over a century, cranes and scaffolding have defined its identity. As we are moving further in 2026, this “never-ending” masterpiece is on the brink of structural completion.

A Century Of Legacy

The year 2026 marks the centenary of Antoni Gaudi’s death. Finishing off with the main structure in this year served as the ultimate tribute to the “Architect of God.” 

In February 2026, the final piece of the central tower of Jesus Christ was placed. At 172.5 meters, the Basilica has officially become the tallest church in the world. It now surpassed Germany’s Ulm Minster, a record-breaking feat over a hundred years in the construction process.

From 19th-Century Plans To 21st-Century Tech

The entire construction process took over a century due to back to back historical setbacks. During the Spanish Civil War, Gaudi’s original models were destroyed. Architects had to resume the construction process from charred fragments and old photographs, slowing down the progress for decades.

Today, the pace has accelerated through a blend of traditional and high-tech engineering. CNC machining carved stone panels with mathematical precision. 3D printing prototypes the complex “ruled surfaces” that gives the church its organic and forest-like interiors.

What To Expect After 2026

While the main towers have finally reached their peak in 2026, the work isn't yet finished. The most monumental feature of the three entrances to the church, “The Glory Façade,” requires intricate sculptural work. However, these decorative events are expected to continue until the end of 2034.
