Wooden scaffolding was to be found at every medieval construction site. A lot of knowledge and experience was needed to make a sturdy and safe construction. Once the scaffolding completed, heavy stone blocks could be moved and lifted, to build cross rib vaults among other things. Two MOT employees guided us trough the process of building wooden scaffolding and some other medieval construction techniques. Scouting Grimbergen teached us to lash a wooden ladder.
