Sagrada Familia Construction Timeline: What's Done, What's Left & When It Finishes

Sagrada Familia in 2026: Is It "Finished" Yet?

The short answer is: structurally yes, fully no. As of 2026, the main structure and all six central towers — including the Tower of Jesus Christ crowned with a massive glass and steel cross at 172.5 meters — have reached their full planned height. The Sagrada Familia is now the tallest church in the world, surpassing Ulm Minster in Germany.

But "architecturally complete" and "fully finished" are not the same thing at the Sagrada Familia. The main skeleton of the building is up. The interior is finished and fully visitable. The stained glass cycles are installed. The Nativity and Passion façades are complete. Yet significant decorative work remains — most notably the Glory façade (the future main entrance), sculptural programs on multiple surfaces, inscriptions, and urban integration around the basilica.

The current consensus among project leaders: structural completion by 2026–2028, full decorative completion — including the Glory façade — extending into the early-to-mid 2030s. No one will commit to a precise final date, which is itself part of the Sagrada Familia story.

140 Years of Construction: Key Milestones

The Sagrada Familia is one of the longest active construction projects in human history — over 140 years and counting. Here are the milestones that matter.

The Gaudí era (1882–1926). The project began in 1882 under architect Francisco de Paula del Villar with a conventional neo-Gothic design. When Antoni Gaudí took over in 1883, he reimagined the entire building with his signature organic, nature-inspired forms. He worked on it for 43 years — the last 12 exclusively — but by the time he was struck and killed by a tramway in 1926, only the crypt, the apse, and one tower of the Nativity façade were complete. His plaster models and drawings became the roadmap for everything that followed.

The slow middle decades (1926–1980s). After Gaudí's death, work slowed dramatically. The Spanish Civil War (1936–1939) destroyed many of his original models and workshop drawings. Construction resumed gradually using surviving fragments, photographs, and the institutional memory of collaborators who had worked alongside Gaudí. For decades, progress was funded almost entirely by private donations and growing tourism. By the 1970s, the Nativity façade was complete but the building was still far from finished.

The digital acceleration (1980s–2010s). The adoption of computer-aided design, new materials, and prefabrication techniques transformed the pace of construction. Gaudí's complex hyperbolic and paraboloid geometries — nearly impossible to build by traditional methods — could now be modeled and fabricated digitally. In 2010, Pope Benedict XVI consecrated the completed nave as a basilica, and the project crossed the symbolic "halfway" mark. The interior that visitors experience today was essentially finished during this period.

The tower era (2010s–2026). The final push to raise the six central towers — four Evangelists, the Virgin Mary, and Jesus Christ — defined the most recent decade. The Tower of the Virgin Mary was completed in late 2021 with a luminous star at its peak. The four Evangelist towers reached their full height in the following years. In February 2026, the installation of the cross on the Tower of Jesus Christ at 172.5 meters brought the church to its full planned silhouette — the most significant visual milestone since the nave was consecrated.

What's Already Finished and Fully Visitable

For visitors in 2026, the experience of the Sagrada Familia already feels architecturally complete. Here is what you can see and access today:

The interior nave. The forest of branching columns, the soaring central vault, and the full cycle of stained glass windows are finished and visitable from end to end. This is the space that makes the Sagrada Familia unlike any other building in the world — a cathedral-scale interior where every structural element is modeled on natural forms.

The Nativity façade (east). The oldest and most Gaudí-authentic exterior surface, completed largely during his lifetime and in the decades immediately after. Dense with sculptural detail — carved stone vegetation, animals, angels, and scenes from Christ's birth. Four bell towers rise above it.

The Passion façade (west). Completed in a starkly modern style by sculptor Josep Maria Subirachs, depicting Christ's suffering and death through angular, skeletal forms that contrast dramatically with the Nativity side. Four bell towers, with the Passion tower accessible to visitors.

The six central towers. All reached their full height by 2026, including the Tower of Jesus Christ at 172.5 meters. Visitors can access the Nativity and Passion bell towers by elevator (stairs-only descent). The central towers are not open to public access.

The crypt. Gaudí's burial site, located beneath the apse. Accessible during the visit and containing information about the architect's life, death, and beatification process.

The museum. Models, drawings, photographs, and documentation of the construction process from the 1880s to the present. Includes surviving fragments of Gaudí's original plaster models.

What's Still Under Construction

The remaining work is concentrated in three areas:

The Glory façade (south). This is the most significant unfinished element. Gaudí intended it as the principal entrance — a monumental front facing Carrer de Mallorca — with a massive portico, stairway, and sculptural program representing humanity's journey to God. As of 2026, structural elements are advancing but the façade is far from complete. The surrounding streets require reconfiguration (including the demolition of some buildings) to create the open approach Gaudí envisioned.

Decorative and sculptural work. Even on the structurally complete façades and towers, ongoing work continues on inscriptions, ornamental details, pinnacles, and secondary sculptural elements. Gaudí's original vision called for a level of surface decoration that extends well beyond the structural skeleton — every column capital, every exterior surface, every transition between elements was designed to carry symbolic meaning.

Urban integration. The area immediately surrounding the basilica is part of the long-term project: pedestrianization, landscaping, and creating the public spaces that frame the building as Gaudí intended. This work depends on coordination with Barcelona city planning and will extend beyond the basilica itself.

When Will the Sagrada Familia Actually Be Finished?

This question has been asked for over a century, and the honest answer remains: nobody knows precisely.

The most widely cited current estimate: main structural works complete by 2026–2028, with the Glory façade and final decorative completion extending into the early-to-mid 2030s. Some project leaders have mentioned 2032 (the 150th anniversary of the first stone) as a symbolic target, but no one will commit to a firm date.

This is partly because the timeline has shifted repeatedly throughout the project's history. Predicted completion dates have moved due to funding fluctuations, technical challenges, the Spanish Civil War, and most recently the COVID-19 pandemic, which paused construction entirely in 2020 and reduced the ticket revenue that funds most of the work. Any current timeline should be read as a best-case scenario rather than a fixed promise.

But the uncertainty is also part of the Sagrada Familia's identity. This is a building that has moved from hand-drawn models to digital fabrication, survived a civil war, and outlasted its architect by a full century — while still trying to be faithful to his vision. The fact that it is not finished yet is not a failure of planning. It is the nature of a project that was always meant to span generations.

What the Ongoing Construction Means for Your Visit

Construction does not prevent a full interior visit — and for many visitors, it actually adds to the experience.

What you will see: Cranes, scaffolding, and construction barriers are visible around the Glory façade and some upper sections of the building. Inside, the main nave and galleries are unaffected. The construction activity is concentrated on exterior elements and does not interfere with the standard visitor route.

Why 2026–2030 is an especially interesting window: As the project enters its final phase, the Sagrada Familia is adding more interpretive material about the construction timeline — temporary exhibits, updated museum content, and before-and-after displays that show how specific sections evolved from Gaudí's models to finished stone. Visiting now means you can see a building that is simultaneously a completed masterpiece and an active construction site — something that will not be possible once the last scaffold comes down.

For architecture and history enthusiasts, the construction itself is part of the attraction. Watching the Glory façade take shape, seeing modern prefabricated stone elements being hoisted into position, and standing inside a building that has been under continuous construction for 140+ years — this is a dimension of the Sagrada Familia that future visitors, after full completion, will never experience.
