The ruins seen through the trees and across the moat are probably that of the undershot wheel water mill that stood on this site. Unusually the milling business had dual power there was also the substantial remains of a wooden windmill on the site until it collapsed during a gale in November 1977. NB there is a mistake on older OS maps that refer to Ockenden Hall rather than Ockendon, a common mistake.
