1. LEGO Art World Map (31203) – 11,695 Pieces

The largest LEGO set ever made is the LEGO Art World Map, which requires 11,695 pieces in total to assemble. It’s a literal piece of art with a mosaic design and allows builders to customize the layout of the world’s oceans or landmass to refocus the map on 1 of 3 sections of the world.

The completed World Map becomes one of the most enormous LEGO wall displays through its dimensions of 25.5 inches (65 cm) height and 40.5 inches (104 cm) width. All its elements consist primarily of small 1×1 LEGO building blocks to achieve this complex construction. 

Builders who complete the task can enjoy the soundtrack that comes with the set. The set was initially available in June 2021 for $249.99 / £229.99 / €249.99, but now, since it is retired, it costs double that.
