Oystermouth Castle (Gower)
It is said that in an underground dungeon of Oystermouth Castle is, or there was, a large pillar known as “The Wishing Post,” around which young men and young women, when wishing for a lover or sweetheart, were in the habit of walking nine times, and at the same time sticking a pin in the pillar and looking on the wall, when they were supposed to see “a lady in white.”
