Colosseum
£450 / 9036 pieces
Rome wasn’t built in a day, say smug people. The same is true for Lego’s Colosseum, unless you’re a real brick wizard, what with it having the largest Lego piece count to date.
Still, you’ll have reason to feel smug after working through its 60+ bags of parts, most of which are the same colour. Don’t tip them all into a massive bowl, then, unless you’re the type who enjoys doing huge Star Wars sets while lost in a sea of grey.
