A planning application for the erection of nine houses and a community hall with associated parking and landscaping, following the demolition of existing church and dwelling at Hall Grove, Welwyn Garden City, was granted by Welwyn Hatfield Borough Council. Albion Archaeology was commissioned to undertake a trial trench evaluation of the proposed development area. Six trenches were opened, sampling c.5% of the site. Archaeological features were identified in two of the six trenches; these comprised two gullies, two pits, a ditch and two postholes all located within Trenches 2 and 3. The nature of a very small sherd of pottery recovered from one of the gullies within Trench 2 suggests the gullies and posthole within this trench could possibly date to either the Roman or medieval period. The proximity of Ludwick Hall suggests the latter of the two dates is more likely, though this must remain conjecture due to the very small size and abraded nature of the potsherd. A fragment of a flint core also recovered from the gully within Trench 2 could be derived from late Neolithic-early Bronze Age activity within the wider surroundings of the site. The limited and largely undated evidence does not allow for too much interpretation as to the nature or significance of the archaeological features revealed. However, the paucity of the finds does suggest that these features are peripheral to any settlement activity and more likely to be associated with agrarian or other rural activities.
