Wooden model kit inspired by Leonardo da Vinci’s famous Revolving Bridge (Codex Atlanticus, folio 855r). Precisely laser-cut, it includes components in birch plywood (4 mm), structural parts in poplar plywood (8 mm), and elegant walnut-effect veneer details (1 mm). Assembly requires PVA glue (not included). Once assembled, the bridge delights with its graceful movement: the parabolic arch smoothly revolves 90° through a system of pulleys operated by a manual winch shaped like a small cross. Perfect for hands-on exploration of Renaissance engineering principles, this model beautifully blends art, mechanics, and design. Refined and enjoyable to handle, it ranks among DAHIMO’s best-selling kits in museum gift shops, highly valued by history lovers, mechanical enthusiasts, and model-building fans.
