Stonehenge experiment
P A N E L T W O
Transporting a large stone
All the stones that make up
Stonehenge were transported over varying terrain from up to 30 miles away. How would this have been done in the Neolithic Age and could it be done
with limited manpower?
The team tried various methods. Hauling a concrete replica block with timber rollers underneath it was tested but the rollers were crushed by the weight and got stuck in the mud. Plus directional control was difficult.
The most successful method was the use of a timber sledge to haul the block along a greased timber slipway.

The sledge
Made of oak a slab 5m long,
1m wide and 300mm deep,
with a chamfered leading edge.
A rectangular
section keel was
attached to the
underside to secure
the sledge to the
20mm square-section
slipway. A proprietary
grease, chosen for its
similarity to tallow
(Neolithic equivalent),
was used for
lubrication.
To break the initial resistance caused by the combined friction load and sticking force, two teams of four people rocked the block using levers either side of the leading edge. Others maintained tension on the hauling ropes. Once it started to move, the block was pulled along at a slow walking pace.
