I knew I had a photograph from the late 1980s of Mersey from behind the Albert Dock so I attempted to get the same viewpoint. The most interesting difference is the proliferation of safety fences. In the older photo on the right ther were no barriers other than the chain fence. Now there is a solid railing fence and in places extra barricades - a sign of our mitigation-mad culture? The three dockyard cranes at the Cammell Laird Shipyard at Birkenhead were blown up in November 2003 when the dockyard closed.
