The Dungeon (Liverpool local history)

An interesting piece on the history of the Dungeon, an area of Liverpool close to where my mum lives. I must confess that the name dungeon conjured up for me visions of dank prison cells, however the Dungeon was, in fact a major salt refinery and a place of considerable historical interest, http://www.roydenhistory.co.uk/mrlhp/local/salt/dungeon.htm.
