"The Goban and his son were seven years building the castle, and they
never said a word all that time. And at the end of seven years the son
was at the top, and he said 'I hear a cow lowing.' And the Goban said
then 'Make all strong below you, for the work is done,' and they went
home. The Goban never told the secret of his building, and when he was
on the bed dying they wanted to get it from him, and they went in and
said 'Claregalway Castle is after falling in the night.' And the Goban
said 'How can that be when I put a stone in and a stone out and a stone
across.' So then they knew the way he built so well."
