On your left you will pass the private road leading to Blackwater Sailing Club. The Club House is built on the site which was occupied by the Marine Salt Company in the 19th century.
From here until you reach the junction with Blackwater Close you will be following the line of the old sea wall and all the land to your left was originally saltings or marsh, used for grazing.
Many maps show a tumulus on the marshland close to the Sailing Club gate. Opinions vary as to whether this was a burial mound, a red hill remaining from Roman salt extraction, or possibly a mound built for cattle grazing the marshes to retreat to in times of flood. During WW2 an air raid shelter dug into the mound served local farm workers, In later years village children played on the “high heap”. (Who smoked their first cigarette there?!)
