Captain Kidd's treasure. The Holy Grail. Lost Shakespearian manuscripts. Whatever lies under Nova Scotia’s Oak Island, it’s buried in 210 years of mystery. In 1975, a 16-year-old boy found a strange depression and began digging. To this day, searchers are still trying to outwit a complex tunnel system that floods the pit when they venture too deep. Theories abound on what’s hidden there and who hid it.

Speculation is further fuelled by onsite discoveries, including a tablet claiming the pit contains 2 million British pounds, a Spanish coin dated 1598 and coconut fibres from faraway lands. Six have died in the “Money Pit” since 1975.
