Three body sherds of a Peterborough style bowl, decorated with horizontal lines of irregular oblique fingernail impressions. Found during archaeological excavations at 'Caesar's Camp', Heathrow in 1944. The enclosure was found to contain 11 Iron Age roundhouses and a small rectangular shrine or temple. It was the first site of its type to have been totally excavated. The name ‘Caesar’s Camp’ is an 18th-century invention. Early maps refer to it as Shasbury Hill, which may derive from the old English sceaceres byrig, meaning ‘robber’s fort’. The site now lies beneath the eastern end of the main northern runway at Heathrow Airport.
