In page Wirral Peninsula:

"

Before the time of the Romans, Wirral was inhabited by a Celtic tribe, the Cornovii. Artefacts discovered in Meols suggest it was an important port from at least 500 BC. Traders came from Gaul and the Mediterranean localities to seek minerals from North Wales and Cheshire.[2] There are remains of a small Iron Age fort at Burton, for which the town was named (burh tún being Old English for "fort town").[1]
