LEGO has unveiled the largest building set in its history, a 12,060-piece replica of Barcelona's Sagrada Família priced at $799.99. The Architecture series model recreates Antoni Gaudí's masterpiece with special stained-glass effects and will ship November 1, 2026.

The 12,060-piece set follows the basilica's actual construction sequence, beginning with the Apse with Crypt and the Nativity façade. Builders can track progress using the LEGO Builder app with 3D instructions, rotating views, and saving capabilities. Measuring over 24 inches tall, this premium set offers a challenging build for adult enthusiasts.

Despite the premium price point, LEGO Insiders members can earn 5,200 points with purchase, redeemable for discounts or exclusive sets. The collectible model serves as both an architectural display piece and a creative challenge for travel and history enthusiasts seeking hands-on activities.
