Bbrockley Hill in Middlesex lies one mile south of Elstree Village and is bisected by Watling Street, which now forms the boundary between the London Boroughs of Barnet and Harrow. It is generally considered to be the site of Sulloniacae which was mentioned in the Second Antonine Itinerary as lying twelve miles from Londinium and nine miles from Verulamium. Excavations from 1937 to 1974, whilst failing to confirm this, have provided evidence of a flourishing coarse-pottery industry there in the first and second centuries. The manufacture of bowls, flagons, jars (some with lids), mortaria, platters and tazze is well attested.
