Construction Update: The Path to Completion in 2026

On the morning of 20 February 2026, construction workers hoisted the final element into position atop the Sagrada Família: the upper arm of a four-armed cross, measuring 4.5 by 4.5 by 4.9 metres, that now crowns the Tower of Jesus Christ at a height of 172.5 metres above Carrer de Mallorca. It was a moment 144 years in the making — the longest-running building project in the modern world reaching, at last, its full external silhouette.

For the first time since the foundation stone was laid on 19 March 1882, the Sagrada Família's skyline is complete.

This Sagrada Família construction update covers everything you need to understand about what that completion means: what was built and when, what the 2026 centenary inauguration involves, what sections of the building are still under active work, and why this particular moment — right now, in 2026 — is a genuinely unrepeatable time to stand inside Gaudí's masterpiece.

The Milestone: February 20, 2026

The significance of the February 20 date cannot be overstated. The Tower of Jesus Christ is not simply the tallest of the Sagrada Família's 18 towers — it is the structural and spiritual centre of everything Gaudí designed. At 172.5 metres, it makes the Sagrada Família the tallest church in the world, surpassing the Ulm Minster in Germany, which held that record since the 19th century. It is also, deliberately, 5.2 metres shorter than the hill of Montjuïc, which rises to 177.7 metres above sea level. Gaudí's reasoning was deeply personal and entirely characteristic: he believed no human creation should surpass the work of God. The height of his central tower is a philosophical statement encoded in stone and steel.

The cross itself stands 17 metres tall — the equivalent of a five-storey building — and spans 13.5 metres in width. Each of its four arms was lifted into position in sequential sections across several weeks, with the upper arm — the final piece — installed on 20 February. Inside the upper arm, at its highest point, a sculpture of the Agnus Dei by Italian artist Andrea Mastrovito awaits permanent installation: the lamb that Gaudí envisioned at the centre of the cross, visible from within the structure itself.

With that installation, the ensemble of the six central towers was externally complete for the first time. The building that had defined Barcelona's skyline as a permanent work-in-progress, surrounded by cranes for most of living memory, had become something new: a finished vertical forest.

The Centenary: June 10, 2026

The Tower of Jesus Christ reaching its full height in February 2026 was the architectural milestone. The centenary events of June 2026 are the ceremonial ones — and they are extraordinary in their own right.

On 10 June 2026, exactly one hundred years after Antoni Gaudí died in Barcelona, Pope Leo XIV will preside over the solemn Mass and official blessing and inauguration of the Tower of Jesus Christ inside the Sagrada Família. It is the first papal visit to Barcelona in fifteen years, the last having been Pope Benedict XVI's 2010 consecration of the basilica. That 2010 visit generated a 38% increase in visitor numbers in the months that followed. The centenary event of June 2026 is expected to eclipse it entirely in terms of global attention and historical significance.

The full programme for June 9 and 10 includes:

• A private flower-laying ceremony at Gaudí's tomb in the basilica crypt at 10:00 AM on June 10, marking the exact hour of the centenary

• A solemn Mass inside the nave of the Sagrada Família, co-celebrated by cardinals, bishops, and priests and accompanied by choirs from across Catalonia

• The official blessing of the Tower of Jesus Christ by Pope Leo XIV

• An evening light show projected onto the façades, visible from the surrounding streets

• A vigil event at the Lluís Companys Olympic Stadium the previous evening on June 9

A significant clarification for visitors planning around this date: the June 10 inauguration is a religious ceremony, not a public opening of the tower to visitors. The tower's observation viewpoint at 164 metres — which will have capacity for eleven people at a time — is expected to open to the public in 2027, not in the centenary year. The area surrounding the basilica from June 6 through June 12 will experience extraordinary crowd levels due to the papal visit to Spain running across those dates.

The centenary also coincides with Barcelona being named the UNESCO World Capital of Architecture for 2026. The city is hosting an extended programme of architectural exhibitions, cultural events, and Gaudí retrospectives throughout the year. The Sagrada Família itself features as the centrepiece of the exhibition "La Sagrada Família and Barcelona: 144 Years of a Shared Journey," running from 27 April to 26 July 2026 at the Jardins del Palau Robert near Passeig de Gràcia, with free admission.

How the Basilica Was Funded: The Story Behind the Construction

Understanding how the Sagrada Família has been built — and continues to be built — adds a dimension to any visit that most tourists never encounter. From the very beginning, Gaudí refused state or church funding, insisting that the temple be financed entirely through private donations and public subscription. He wanted it to be a genuinely popular project: a building belonging to all people rather than to institutional power.

That model persisted through every era of construction. For most of the 20th century, progress was agonisingly slow — the Spanish Civil War brought construction to a halt entirely and, in 1936, a fire in the crypt destroyed many of Gaudí's original plans, plaster models, and drawings. The reconstruction of those lost plans from photographs and surviving fragments became an architectural detective project that consumed decades.

The funding model transformed in the early 21st century, when Barcelona's emergence as one of Europe's most popular tourist destinations created a stable and growing revenue stream through ticket sales. Since 2015, visitor revenue has contributed the majority of annual construction funding, typically running between €25 and €35 million per year. This is why your Sagrada Família ticket purchase is not merely a transaction — it is a direct contribution to the completion of one of the most ambitious cultural projects in human history. Every entry fee, every guided tour booking, every tower access upgrade has helped lift those cranes and place those towers.

The 2026 centenary year is expected to generate record ticket revenue, which the Foundation intends to direct toward the next phase of work: the Glory Façade.

What Was Completed and When: A Construction Timeline

The Sagrada Família's 18 towers are the clearest way to track the progress of construction across decades. Each tower represents a specific biblical figure, and their completion sequence tells the story of a building assembled almost entirely from the back and the sides before finally reaching its centre.

The key milestones in chronological order:

• 1882: Foundation stone laid by Bishop José María Urquinaona on 19 March, feast of Saint Joseph

• 1883: Antoni Gaudí takes over as chief architect at age 31, radically transforming the original neo-Gothic plan into something entirely without precedent

• 1926: Gaudí dies on 10 June after being struck by a tram on the Gran Via. At his death, between 15% and 25% of the building is complete — primarily the crypt, the apse, and the lower sections of the Nativity Façade

• 1936: Fire in the crypt during the Spanish Civil War destroys original plans, drawings, and plaster models. Reconstruction of Gaudí's intentions from photographic records begins immediately after

• 2000: The Nativity Façade towers, the oldest section of the building, are restored and completed after decades of work

• 2010: Pope Benedict XVI consecrates the Sagrada Família as a minor basilica. The interior is sufficiently complete for regular worship. The building is simultaneously a consecrated church and an active construction site — unique in modern religious history

• 2021: The Tower of the Virgin Mary is completed, lit with a distinctive twelve-pointed luminous star visible across Barcelona on its first night of full illumination. This was a moment of particular emotional weight for the city

• 2022: The four Evangelist towers — Matthew, Mark, Luke, and John — are completed, surrounding the position that the central Tower of Jesus Christ would occupy. Each is topped with the symbolic figure of its respective Evangelist: a human, a lion, an ox, and an eagle

• November 2023: The Apostle towers of the Nativity Façade are fully restored, completing the facade ensemble

• February 20, 2026: The upper arm of the cross atop the Tower of Jesus Christ is installed. The building reaches its full height of 172.5 metres. The exterior of the Sagrada Família is structurally complete

What Remains: The Work Ahead to 2034

The February 2026 structural completion is real and historic. But it does not mean the building is entirely finished, and any honest Sagrada Família construction update must be clear about what work continues.

The distinction to understand is between structural completion — the towers and façade architecture — and full completion, which includes decorative elements, interior finishing, and the most complex remaining project: the Glory Façade.

Interior finishing and tower detailing: Interior work within the Tower of Jesus Christ will continue through 2027 and 2028. The nave and crossing spaces also retain areas of ongoing decorative work — the installation of additional stained glass sections, sculptural elements along the interior column systems, and refinements to the acoustic and lighting design of the space.

The Chapel of the Assumption: Begun in recent years adjacent to the main basilica, the Chapel of the Assumption is in active construction and forms part of the broader sacred precinct that Gaudí envisioned surrounding the central structure.

The Baptistery: Foundations for the future Baptistery were begun in 2024 and continue into 2026. This will eventually occupy the south-west corner of the basilica's footprint.

The Glory Façade: The most significant remaining project by far — and the most contested. The Glory Façade on Carrer de Mallorca is intended to be the main entrance to the Sagrada Família, the grandest of the three façades, representing the path to God through Death, Final Judgement, and Glory. Gaudí's original 1916 sketches envisioned a monumental staircase and terrace sweeping across an entire city block, with around 100 individual sculptures integrated into the composition.

The obstacle is an urban planning reality that Gaudí could not have anticipated in his lifetime: the buildings on the opposite side of Carrer de Mallorca, constructed across the 20th century, now occupy the space that the original design requires. As of May 2026, negotiations between the Sagrada Família Foundation and the Barcelona City Council regarding the future of these buildings — and the compensation of their residents — are ongoing. The Glory Façade sculpture programme and the monumental staircase are projected to continue until 2034 or 2035. The Glòria staircase and the surrounding urban integration elements may extend even beyond that.

This means that a visit to the Sagrada Família in 2026 includes one sight that will not be available in 2034: construction. The cranes are not entirely gone. The scaffolding remains in certain sections. Some visitors find this disappointing. Others — rightly, we would argue — recognise it as the last opportunity to see a building in the process of becoming itself, before the final chapter closes and it stands in its complete silence.

What Visiting in 2026 Means for You

The Sagrada Família construction update for 2026 ultimately answers a practical question that every potential visitor is asking: is this a good year to go?

The answer is emphatic and unconditional: yes. Here is why 2026 is the most significant year to visit since the basilica was consecrated in 2010 — and arguably the most significant since Gaudí died in 1926.

• The Tower of Jesus Christ has reached its full height for the first time, and the completed 172.5-metre skyline can now be seen and photographed from across Barcelona

• The interior light calibration — the way the final stained glass installations of the central tower now interact with the nave — is fully operational for the first time, creating the colour environment Gaudí designed and that no previous visitor has experienced exactly as he intended

• The centenary programme of events, exhibitions, and cultural activities runs throughout the entire year, making any 2026 visit part of a broader historical moment

• The June 10 papal blessing and inauguration represents one of the most significant single events in the building's 144-year history — even for visitors not present on that specific date, its energy shapes the entire year

• The museum has been upgraded for the centenary year, including a permanent virtual reality exhibit titled "The Completed Vision" showing what the Sagrada Família will look like in 2034 once the Glory Façade is fully realised

For visitors who want to understand the construction story while they are inside the building, both the guided tour and the audio guide app now include specific 2026 centenary content covering the Tower of Jesus Christ, Gaudí's original vision for the height and symbolism of the central spire, and what continues after 2026. Our guide to Sagrada Família group tours explains the tour formats in which this content is delivered most effectively — particularly the small group and architect-led private tours, which go furthest into the technical and symbolic depth of the 2026 completion.

Gaudí's Vindication: A Note on What This Completion Means

Antoni Gaudí knew he would never see the Sagrada Família finished. He said so openly. When asked about the slow pace of construction, he replied with characteristic serenity: "My client is not in a hurry." He spent the last twelve years of his life living in near-poverty in a small room adjacent to the construction site, dedicating every hour and resource to the building. He was struck by a tram on 7 June 1926 while on his way to the site and died three days later on 10 June, at the age of 73.

He is buried in the crypt beneath the nave, in the Chapel of Our Lady of Carmel, a few metres below the floor of the church he never saw finished. In April 2025, the Vatican officially declared Gaudí Venerable — the first formal step on the path to beatification, recognising his life of exceptional Christian virtue. The centenary inauguration by Pope Leo XIV on 10 June 2026, directly above Gaudí's resting place, carries a weight that goes beyond architecture.

What the 2026 completion represents is not just the finishing of a building. It is the realisation, across five generations and 144 years, of one person's act of faith that something extraordinary was possible — that if you began it and kept faith with the vision, it would eventually stand.

That is what you are visiting when you book your Sagrada Família tickets for 2026. Not just a building. A promise that was kept.
