A ghostly White Lady is supposed to have killed a greedy treasure seeker in these ruins. On his first visit he had encountered the ghost and tried to speak to her for which he was rewarded a few coins from the treasure she guards. He made a return visit to alleviate her of the burden of looking after so much treasure, but was caught by the White Lady who scratched him. This scratch was blamed for the man wasting away and shortly afterwards dying.
There are a series of stepping stones that cross the Ogmore and Ewenny rivers by Ogmore Castle. Legend has it that they were built to assist a girl who was living in the castle and deeply in love with a man in Merthyr Mawr beacuse the rivers were too dangerous to cross.
The castle dates from 1116 and was built by William de Londes.
