The Grand Shaft - Dover - Western Heights

The Grand Shaft was built into the white cliffs of Dover to assist the movement of troops between the barracks at the top of the cliff, and the town and harbour below.
Completed in roughly 1807, the shaft entailed building two brick-lined shafts, one inside the other. In the outer, there is a triple staircase, the inner acting as a light well with windows cut in its outer wall to illuminate the staircases.
