From the historical guide to merstham
“Field terraces on the southern slope of the North Downs overlooking the stone quarries at Merstham suggest the area was inhabited and cultivated perhaps as early as pre-Roman times. It is fairly certain that the Romans quarried here. The original entrance to one of the quarries was lined to form two continuous arches. Every stone in the smaller arch was inscribed with the Roman numeral VII and it is thought that the Roman VII legion was responsible for this quarry.”
