Skyline. Bristol Docks. Underfall Yard.

To the left is the outline of one of the 3 Bonded tobacco warehouses - an historic part of Bristols rich (in every sense of the word) trading history.

The other outlines are part of the hydraulic system once used to power facilities in the docks. I have been told by people involved in the dock that it was much more reliable than the modern systems which have replaced it. It is now part of a conservation area.
