Two seasons of excavation by G H Cole for Surrey Heath Group of SyAS. The first located extensive probably late IA to early RB bronze and iron slag and related deposits, a large IA ditch, a 3rd century RB timber framed structure, a post-4th century palisade and plank-formed building and various later RB ditches. Some 5.4m of the timber sole plate of the 3rd century building survived as charcoal. (208) The second season concentrated on the area of RB structures and ditches, indicating a number of 3rd-4th century buildings and identifying at least two timber-built structures later than the late 4th century and thought to be Saxon.
