A well-preserved example of a tidal water mill dating to sometime between 684 and 720 AD. It was found in association with a mill pond, water trough and wattle revetments/fish traps. The dual-chuted construction of the mill and the size of the wheel-pit suggests that horizontal wheels would have powered the mill. it does not seem to have been use for long before it was demolished possibly due to rising water level and silting. A number of the timbers are currently under conservation. Preliminary investigation has revealed a number of axe marks and on one of the larger chute timbers compass marks; evidence of the use of geometry. A wattle screen was identified 1m south of the pentrough inlets. The bases of the rods were sharpened which implies the screen was originally pushed into the pond bed. To the south of the screen a substantial 'Y' shaped pile was identified partly upright. Location accurate to 2m based on available information.
