The north slopes below Edinburgh Castle

The north slopes below Edinburgh Castle is a castle, fort or tower in City of Edinburgh, Scotland. Perhaps people climbed these steep stones before roads existed, carrying water or firewood while watching shadows move across the rock. Maybe the slope itself was the first room, with rain washing dust into valleys and sunlight returning at noon. Imagine a hand pressing against cool stone, not knowing whether it touched a wall, a cliff or the edge of the world.
