Sagrada Familia Facts: Barcelona’s Basilica in Progress

Barcelona’s basilica that kept growing

Sagrada Familia facts start with a church that has never stopped shaping Barcelona’s skyline. In the Eixample district, the Sagrada Família stands as a Catholic basilica and, with the completion of its central tower, the tallest church in the world.

Construction began on 19 March 1882, when Francisco de Paula del Villar started the project. A year later, in 1883, Antoni Gaudí took over as chief architect after Villar resigned, and he devoted the rest of his life to the basilica. When Gaudí died in 1926, less than a quarter of the project had been completed.

Gaudí is buried in the church’s crypt, keeping his name tied to the building in the most literal way. The basilica’s long construction history is part of what makes the Sagrada Família so easy to recognize, even before its final form is complete.

How Gaudí shaped the design

Gaudí’s original design called for eighteen spires in all: twelve for the Apostles, four for the Evangelists, one for the Virgin Mary, and one for Jesus Christ. By 2026, fourteen spires had been completed, leaving the project still linked to the full vision Gaudí drew up.

The church’s façades show that same slow, layered timeline. The Nativity façade was built between 1893 and 1936, and it was the first façade to be completed. The Passion façade began construction in 1954, and its steeples were finished in 1976.

One of the most striking later additions came on 29 November 2021, when a 7-metre twelve-pointed illuminated crystal star was installed on one of the main towers dedicated to the Virgin Mary. That detail sits alongside the older stonework, adding another date to the basilica’s long record of building phases.

When did Sagrada Família become a World Heritage Site?

Parts of the Sagrada Família were declared a UNESCO World Heritage Site in 2005, including the Nativity façade and the Crypt. Those sections connect the basilica not only to Barcelona, but also to the wider recognition of Gaudí’s work.

The project reached another milestone in 2010, when construction passed the midpoint. That same year, on 7 November 2010, Pope Benedict XVI consecrated the church. The basilica was no longer just a construction site or a landmark in progress; it had also taken its place as a consecrated Catholic church.

The timeline of the building keeps stacking up in clear stages: start in 1882, Gaudí’s takeover in 1883, partial completion at his death in 1926, World Heritage recognition in 2005, consecration in 2010, and a new phase of tower completion years later.

Why does the tower matter?

The central Tower of Jesus Christ reached structural completion on 20 February 2026, and that changed the basilica’s place in the skyline. At 172.5 metres, the tower makes Sagrada Família the tallest church in the world.

That height gives the basilica a sharp visual identity, but it also fits the plan Gaudí left behind. The tower belongs to the eighteen-spire design, where the tallest element crowns the whole composition. By 2026, fourteen spires were complete, and the central tower of Jesus Christ had become the defining vertical line of the church.

Even with that achievement, the Sagrada Família remains a story of staged construction rather than a single finished unveiling. Its history runs through architects, façades, tower milestones, and dedications, all anchored in Barcelona’s Eixample district.
