Cornish Bronze Age boat project

Archaeologists in Cornwall believe they have evidence that shows Bronze Age traders were maritime travellers and used hollowed-out wooden boats to cross the English Channel and buy and sell metals.
The Nebra Sky Disc - thought to be one of the oldest Bronze Age representations of the cosmos - was found in a field in Germany, but gold symbols on the bronze disc have been identified as coming from the Carnon Down mines in Cornwall.
The type of boats used by the Bronze Age traders are being recreated for a project at the National Maritime Museum in Falmouth.
