In the late-18th and early-19th centuries, a highwayman by the name of Willie Brennan was operating in the south of Ireland. He is said to have been an honourable man, robbing from the rich to give to the poor. This Irish Robin Hood was not to enjoy a long life, however. After robbing the mayor of Cashel, Brennan was caught and hanged.

Before his execution, he was asked where he had hidden the mayor’s money – he claimed it was in the Three Doons. To this day, it has not been found.
