Swanscombe is a small town in the Dartford Borough of Kent in the United Kingdom. It borders the Gravesham Borough. It is located north-west of Gravesend. Bone fragments and tools, representing the earliest humans known to have lived in England, have been found from 1935 onwards at the Barnfield Pit about 2 km (1 mile) outside the village. This site is now the Swanscombe Heritage Park. Finds from this site include 400,000-year-old skull fragments of hominids (possibly Homo erectus) and an extinct species of elephant.
