Old seawater evaporation building and windmill

A very old industrial site now gone back to nature.

The windmill was used to draw seawater from the foreshore up into tanks housed in buildings like the one in the foreground.

Coal fires fueld from local fields were then lit under the tanks and over time the water was evaporated off leaving the salt.

Salt was an important preservative agent right up into the 1900's.
