The Curragh of Kildare
Legend has it that one day Saint Brigid, the patron Saint of Kildare, was out walking when she met a local nobleman, who owned the lands she was walking upon.
Appealing to the nobleman's generosity she asked that he donate some of his lands to the poor, for a convent and soup kitchens to be built, to which he replied that she could have all the land that her cloak could cover (cheapskate!).
Brigid removed her cloak, and to the nobleman's amazement, the cloak grew and grew and grew, until it covered many thousands of acres. He had no option but to honour the agreement, and to this day the lands of The Curragh remain the property of the people of Ireland.
