When the Saracens destroyed the ancient Capua in 841, some of their inhabitants moved to the Palmobara hill (the modern Bellon's frazione of Triflisco) founding the town of Sicopoli.
It was discovered by R. Luther on March 1, 1854, and named after Bellōna, the Roman goddess of war; the name was chosen to mark the beginning of the Crimean War.
The first known European to sight the islands was Mathew Boyd of Camberwell, London, Commander of the merchant ship, Bellona, in 1793.
