The view from the platform on top of the outer store (now used by the IoSSCo), showing the barrage of rocks placed there when the harbour was last damaged. Considering the thickness involved and the weight and size of granite which was used to build the Piers, it is worthy of note that since repairs, stones have moved about a quarter inch laterally, despite the barrage and despite the wall's integral strength. This was at a low tide of around 1.3 metres, having come in by 200mm.
