This is it. The biggest LEGO set ever—by number of pieces—is an all-new map of the world created entirely from 2-D tiles. With 11,695 pieces, it measures an impressive 41” X 25.5.” The kit consists of 40 Technic baseplates and mainly 1X1 round tiles. Of course you can customize the map by making your own continents and countries but brick-built pins also allow you to mark out places you’ve been to or want to visit. Recommended for ages 18+.
