I'm not a regular reader of The Sun newspaper, but I enjoyed the travel review they published after renting bikes from Jaunt-E bikes in Keyhaven and riding the seawall along the waterfront to Lymington together with the history of the salt marshes:
"In 1733, there were flames burning day and night, heating 163 giant pans of seawater — all part of one of the country’s largest salt works. Windmills stood in rows, pumping seawater, while ships sailed in and out of the harbour, delivering coal and exporting salt as far as Newfoundland and Norway. The last salt house closed in the 1860s."
Worth a read.
