Discover Kojo's PEFC wooden Bastion kit. Build a fortification straight out of the Middle Ages! This fortress can protect you from any invasion, an army from a neighboring country or a legion of monsters.  Protect your kingdom with the catapults proudly erected on the two guard towers and the superhero on their magic griffin!

This construction game consisting of PEFC wooden plates and clamps made of recycled and biodegradable plastic gives the child the opportunity to learn how to follow the instruction manual to reproduce the proposed model or to use their imagination to build whatever they want! 


Kojo stimulates children's autonomy and fine motor skills. Kojo also allows them to understand geometry and the understanding of angles.

All Kojo packs are compatible, so it is possible to hijack and imagine infinite universes.
