The site of Worthing watermill dates back to at least Saxon days and in about 1100 A.D. Hubert-de-Rye gave the mill and its miller Turstan, to the monks at Castle Acre.
Although the mill is in the parish of Worthing, its adjoining mill house is in the parish of North Elmham.
Both the mill and house were constructed entirely out of brick with a Norfolk pantiled roof. Both the mill and house have been painted white at various times throughtout their history.

Curiously, there does not appear to be any evidence of a lucum, although it is possible that one was once located on the upper level of the gable end.

The iron wheel was 14 feet in diameter and 8 feet wide and drove up to 4 pairs of stones. It was manufactured by Hetherington & Parker of Alton and was installed in 1876 as a replacement of an earler wheel.

A diagram of Worthing Mill's machinery can be seen on the Mill Machinery page.
