Although castles are some of the coolest things you can design with LEGO bricks, there’s one reason they will never be cooler than mechs and vehicles; they are immovable. Spencer Winson adds just a handful of ball hinges to one of his towers and — voila! — who needs royal carriages anymore? And it’s not only the concept of the mech-tower itself that makes the build outstanding, but also the iconic yellow/red/blue color range. The design of the tower was undoubtedly inspired by the legendary 375 Castle set, but have you noticed that the tower in the background is built of Duplo bricks? I must admit I have never seen this double arch Duplo piece before. It is more than 40 years old but still looks stunning in new creations.
