Largest LEGO Set Ever Made Reportedly Coming July 1

The biggest LEGO set ever based on Barcelona’s Sagrada Família basilica is reportedly launching in summer 2026, according to some new insights from a reliable leaker. The upcoming model is expected to include hundreds more pieces than the current largest LEGO set in existence.

The new information comes from the Brick Tap community’s Chief Wiggum, a leaker with a long track record of credible LEGO product insights. The same source just recently shared the purported details of LEGO’s first Pokemon set with minifigures.

21065 Sagrada Família Reportedly Poised to Seize the Title of Largest LEGO Set Ever

The insider’s latest report materialized on March 17, identifying a new set in the form of 21065 Sagrada Família. At 12,060 pieces, the unannounced model is expected to debut as the Danish toymaker’s largest set ever by some margin. 21065 Sagrada Família is reportedly planned to hit the store shelves as part of LEGO’s early summer 2026 product wave, with Chief Wiggum citing July 1 as its official release date. It is expected to retail for $599.99 in the United States, as per the same source.

21065 Sagrada Família is said to be part of the LEGO Architecture theme, according to both the newly emerged leak and separate Brick Tap reporting from January 2026. That stated categorization is notable because the Architecture line has so far largely been known for more compact, display-focused landmark and skyline models rather than replicas competing with LEGO’s biggest collector releases. Nonetheless, a Sagrada Família build on this scale would fit the line’s emphasis on famous real-world structures, even if its reported dimensions suggest something much closer to the company’s ultra-premium showcase sets than a typical Architecture-line release.

The Timing of LEGO’s Rumored Sagrada Família Model Is Not Accidental

The real-life landmark on which the rumored LEGO set is based is a Roman Catholic basilica in Barcelona and the best-known work of Catalan architect Antoni Gaudí. Located in the city’s grid-based Eixample district, Sagrada Família combines elements of Gothic Revival and Catalan Modernism. Construction began in 1882, and Gaudí took over the project the following year, transforming it into a highly symbolic, nature-inspired design defined by soaring towers, sculptural facade, and intricate geometric forms.

More than 140 years later, the church remains unfinished but active. The basilica says construction is still ongoing and has projected completion of the main structure in 2026, while recent reports indicate that the central Tower of Jesus Christ has reached its full external height, with interior and finishing work still remaining. LEGO’s rumored set could thus be based on a relatively finished model of the basilica, commemorating the end of nearly 150 years’ worth of construction.

Another Huge LEGO Set Reportedly Coming Before 21065 Sagrada Família

21065 Sagrada Família is expected to surpass the current largest LEGO set, 31203 World Map, by 365 pieces. It is also not the only massive model the Danish toymaker is expected to debut this year; according to several earlier reports, the still-unannounced 11377 Minas Tirith will rank among the 10 largest LEGO sets ever when it launches on June 1. While it is expected to place sixth, the rumored arrival of 21065 Sagrada Família would push it down to seventh among the company’s largest brick-built models to date.
