On the heath are several springs which give rise to the Mill River, a tributary of the River Deben. All Saints Church stood north of Mill River; it was in ruins by the mid-16th century. Much of this church building survives; the north wall is mainly intact and can still be seen put to a new use as part of the barn of Foxhall Farm. It stands at the top of a slope overlooking one of the backroads that link Foxhall Road with Bucklesham Road. Two enormous buttresses give the game away, as well as an expanse of flint amongst the red-brick. In 1530, Foxhall became an ecclesiastical hamlet to Brightwell.
