The Isle of Thanet, no doubt on account of its proximity to the Continent, has during the flow of the centuries experienced its full share of the tide of human immigration and invasion. The Birchington district in particular appears to have been singled out for settlement in ancient times. Flints ranging in age from Palaeolithic to Neolithic have been recovered from various localities, whilst out on the Flats directly facing Minnis Headland, pottery of Roman, Jutish and Saxon character has been found. The most recent addition to the sequence is the considerable occupation area of Late Bronze Age date found by the late ‘Jimmy’ Beck opposite the Minnis Bay esplanade slipway some 210 yards from dry land. The exact position of the site is marked by a black dot on fig. 1. During the Late Bronze Age, no doubt, the present Minnis Bay Flats, scene of the excavations described in this paper, formed the floor of a seaward extension of the valley flanked on the one hand by the Minnis Headland and on the other by the Rifle Range land, both of which must have stretched considerably further out in the Thames Estuary than they do to-day. The fact that the site could only be excavated between tides, being covered by several feet at high water, imposed a severe limitation on the excavations described in this paper.
