The earliest evidence of human occupation of the Harnham area that I am aware of is an enclosure with storage pits on Harnham Hill which date from the Iron Age. Pottery from two Iron Age periods were found in the pits.
A few hundred yards from the church is a Saxon cemetery, containing 64 graves (men, women and children), mostly from the early 6th century. Iron weapons, saucer brooches and glass and amber beads were found in the graves, and one male grave contained two saucer brooches, a Roman brooch, an iron knife and gold, silver and bronze rings.
St. George's Church dates from the Norman period, and Harnham Bridge (actually in East Harnham) was built in 1244 by Bishop Bingham
