Spelthorne Fire Station, Fordbridge, Kingston Road, Ashford

Strip, map and record excavation by T Collie of SCAU, undertaken in 2016, revealed a complex, Middle–Late Bronze Age/Early Iron Age system of ditches across the east of the site. Oriented north–south/east–west and in places formed of a double ditch, it extended to the centre of the site, where the principal ditch turned west towards the river Ash. The ditches may represent a domestic enclosure, although their generally shallow nature suggests they form part of the wider Bronze Age field system known to extend across a large area of the river Thames gravels both north and south of the river. A series of postholes, of similar date and adjacent to the principal ditch, may represent a roundhouse or open-sided structure. In the north-west of the site, Iron Age settlement activity was defined by three curvilinear ditches, probably eaves-drip gullies associated with a small group of roundhouses. The full extent of the settlement was not revealed as the features extended north, beyond the limits of the excavation. To their east, two large, parallel, linear ditches crossed the site, aligned north-east/south-west. They crossed the Bronze Age ditch system at the corner, defined by the change in orientation of the principal Bronze Age ditch, suggesting that the earlier features may have been extant in the Iron Age. The presence of an Iron Age gully on a similar alignment and orientation to the principal, north–south Bronze Age ditch, may be further evidence of the continued presence of the earlier ditch system. The brick foundations of a small, square, post-medieval structure with an associated brick-lined well and soakaway were also revealed.
