Dunguaire Castle is a 16th-century tower house on the southeastern shore of Galway Bay in County Galway, Ireland, near Kinvarra. The name derives from the Dun of King Guaire, the legendary king of Connacht.
Part of the lore about Dunguaire's Castle is that the Lord of the castle was very generous and he continued this generosity into the afterlife. One example of this is the story about a poor beggar whom King Guaire had often helped in life. The beggar visited the King's grave and said, "King Guaire, even you cannot help me now." Undeterred even by death, the King's skeletal hand dropped several gold coins at the beggar's feet. According to legend, still to this day, if a person stands at the front gate and asks a question, they will have an answer to their question by the end of the day.
