Built in 1776 on an island called The Three Mills. This is the world’s largest surviving tidal mill, and a hidden gem of the industrial revolution. Originally providing flour for the local bakers it was put to many uses until bombed in the Second World War. It was saved from demolition by the Passmore Edwards Museum Trust.
