Caption: Marker detail: Splitting Rocks by Hand
Additional Description: Masons hand-drilled holes into sandstone blocks on this slope. You can still see drill-hole scars today on the walls of Winsor Castle. Wooden pegs were then driven into the holes, and drenched with water. As the wet pegs expanded, the fine-grained sandstone split into blocks.
