12,000-piece LEGO Architecture Sagrada Familia set rumoured

The 12,000-piece LEGO Architecture set rumoured for 2026 is now believed to be a recreation of Barcelona’s Sagrada Familia.

In late 2025, rumours of a 12,000-piece LEGO Architecture model surfaced, leading to some speculation as to what landmark it would depict. Our top pick is now precisely what is rumoured by the reliable a.clay.brick on Instagram. 21065 Sagrada Familia is stated to be released on July 1, 2026, for $600 with 12,060 pieces.

The Barcelona landmark was designed by Catalan architect Antoni Gaudí and has been under construction since 1882. It features his signature complex Art Nouveau style. The main tower is expected to finally be completed this summer, and it reached the maximum height of 172.5 meters with the installation of glass panels last month.

A summer release of a LEGO model for this landmark makes a lot of sense, though it's still only a rumour at the time of writing. The LEGO Store in Barcelona has a recreation of the church as one of its signature models, complete with cranes to show that it's still under construction.

21065 Sagrada Familia would be by far the biggest LEGO set ever, at the rumoured 12,060 pieces. It has joined the list of confirmed and rumoured LEGO Architecture 2026 models for now, of which only 21064 Paris – City of Love is officially confirmed so far.
