21065 Sagrada Família is said to be part of the LEGO Architecture theme, according to both a newly emerged leak from January 2026 and a separate Brick Tap reporting. That classification is notable because the Architecture line is largely known for compact, display-focused Landmarks and more compact, display-focused models than compact Landmarks. The biggest collector's release. However, a Sagrada Família build on this scale would fit the line's emphasis on famous real-world structures, even if its reported dimensions suggest much closer to the company's ultra-premium showcase sets than typical architecture-line releases.

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 Barcelona's Roman Catholic basilica and Catalan architect Antoni Gaudi's most famous work. Located in the city's grid-based Eixample district, the Sagrada Família combines elements of Gothic Revival and Catalan modernism. Construction began in 1882, and Gaudí took over the project the following year, turning it into a highly symbolic, nature-inspired design defined by soaring towers, sculptural facades, and complex geometric forms.
More than 140 years later, the church remains unfinished but active. The basilica says construction is still ongoing and the main structure is expected to be completed in 2026, while recent reports indicate that the central tower of Jesus Christ has reached its full exterior height, with interior and finishing work still remaining. LEGO's rumored set may thus be based on a relatively finished model of the basilica, commemorating the end of nearly 150 years of construction.
Another big LEGO set is coming before 21065 Sagrada Família
The 21065 Sagrada Família is expected to surpass the current largest LEGO set, the 31203 World Map, with 365 pieces. It's not even the only gigantic model the Danish toymaker is expected to debut this year; According to several previous reports, the still unannounced 11377 Minas Tirith will be among the 10 biggest LEGO sets when it launches on June 1st. It is expected to come in sixth place, but the rumored arrival of the 21065 Sagrada Família will push it to seventh among the company's biggest ill-fated models.
