Lego’s latest flagship store opened Thursday in London’s Leicester Square. The two-story megastore—complete with a life-sized London Underground train car made up of 637,903 bricks—is the largest of its kind in the world.
The new Lego store covers 9,800 square feet and contains a 20-foot replica of Big Ben that took 2,280 hours to build (and has a working clock face, naturally). Unique to the new store is a “Mosaic Portraits” system, where participants are presented with instructions and the bricks to create their portrait after having their photo taken in a special booth.
