Captain Kidd was executed in 1701 for piracy after returning from a voyage to the Indian Ocean. Legend had it that Kidd hid much of his loot, which has prompted numerous treasure hunts around the world and inspired Robert Louis Stevenson when he wrote Treasure Island.

Finland’s accomplished diver and wreck researcher Rauno Koivusaari, who discovered the famous treasure ship Vrouw Maria in 1999, has now also found the wreck of the Hanneke Wrome just south of the island of Jussarö in Finland. According to historic documents, the ship was carrying 10,000 gold coins, estimated to be worth around €50 million today.
