Park Brow is a ridge of the South Downs, running roughly north and south. The southern end of the hill, upon which three early inhabited sites have been found, abuts on the valley from which rises the higher hill crowned by Cissbury camp. On Park Brow there is clear evidence of the presence of man in ancient days. Very many lynchets or steep banks are found, a sunken trackway runs along the southern crest of the hill, adjoining which, where it passes the Early Iron Age site, is seen an embanked pit; while over the greater part of this area, as well as in the adjoining valleys, fragments of ancient pottery, rough flint scrapers, and other implements, together with many flint flakes, can be picked up.
