The Island
The "island" (which is technically an isthmus) was once known as Pendinas. This is the Cornish for "fortified headland".
Consequently, and given the ideal geography, it is thought that there might have been an Iron Age promontory fort here. No archaeological remains have been recorded but the island has been heavily altered during centuries of military and urban construction, so they could have been obliterated by that.
Another possibility for the name is from mediaeval/Tudor fortifications to protect the town from French pirates. A small stone fort (known as "the castle") was built near the base of the headland, at the end of the 15th Century, to house a battery of cannons.
