Perforated clay slab of unknown function. Large numbers of these have been found in the Thames valley. This example was found during archaeological excavations of a settlement 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.
