To mark the centenary of Antoni Gaudí’s death, LEGO has announced its most ambitious set to date: a 12,060-piece model of the Sagrada Família that becomes, by piece count, the largest LEGO building set ever produced. The LEGO Architecture Sagrada Família (21065) replicates the Barcelona basilica at a scale and level of detail that places it squarely at the intersection of collectible object, architectural scale model, and historical document — and does so one hundred years after the death of the architect who devoted the final four decades of his life to a building that remains, to this day, unfinished.
The build sequence is the set’s most considered decision. Rather than constructing the model from the ground up in the most structurally efficient order, the LEGO design team — led by Rok Žgalin Kobe — structured the assembly to mirror the actual construction sequence of the Sagrada Família. The build begins with the foundational Apse and Crypt, moves through Gaudí’s original Nativity façade and the Passion façade, rises through the grand naves, Western Sacristy, and six towers, and concludes with the Eastern Sacristy and the Glory façade — the section of the real basilica that remains under active construction. The builder traces the building’s history rather than simply assembling its form.
The formal complexity of the Sagrada Família made this a genuinely difficult design problem. Gaudí’s structural language — based on ruled surfaces, hyperbolic paraboloids, and organic forms drawn from nature — does not translate easily into rectangular interlocking bricks. The 12,060-piece count is a direct consequence of that ambition: it surpasses the previous record holder, the LEGO Art World Map at 11,695 pieces, and reflects the density of detail required to render the basilica’s towers, facades, and interior geometry with any credibility. “Balancing scale and precision, while remaining faithful to a living monument that has been evolving for more than a century, was a unique design challenge,” says Žgalin Kobe.
One distinctive element is the stained-glass window effect built into the model using translucent coloured elements — a reference to the basilica’s celebrated chromatic light, which Gaudí designed to shift from warm amber and red on the western side to cool blue and green on the east as the day progresses. The translation is inevitably metaphorical rather than literal, but it gives the completed model a visual specificity that distinguishes it from a purely structural reproduction. Once assembled, the model stands over 62 centimetres tall, 47 centimetres wide, and 39 centimetres deep — a display piece designed to be read from every angle.
The set joins the LEGO Architecture portfolio, which has built a consistent audience among adult builders, architecture enthusiasts, and design collectors over the past two decades. The Sagrada Família set is the most complex entry in that catalogue — not only in piece count but in the conceptual weight it carries. Commemorating the centennial of Gaudí’s death with a model of his still-unfinished masterwork is a curatorial decision as much as a product one. The LEGO Builder app provides 3D instructions and progress tracking to support the build process.
The Gaudí centenary has generated significant institutional attention across Spain and internationally in 2026, with exhibitions, publications, and heritage initiatives marking the hundred-year anniversary of his death on 10 June 1926. The Sagrada Família itself — under continuous construction since 1882 — remains the most visited monument in Spain and one of the most recognizable buildings in the world. Its projected completion, long delayed, is now anticipated within the next few years, meaning this LEGO set arrives at a moment when the gap between the model and the finished building may finally be closing.
