In the early 19th century Penylan Well (at Twgwyn Farm) was said to be haunted by a Lady in Black who could frequently be seen there wailing and moaning. Eventually a man stopped and spoke to her. She told him that if he held her by the waist and remained silent whatever happened, she would be released from bondage (it being thought that the firm hand-clasp of a 'pure-minded' man could do this for the spirits of the departed - as could the kiss of a new-born baby). The man did as he was asked and put his arm around the woman's waist. Almost at once, however, he felt a sharp, stabbing pain in his arm and was forced to let go of her. The Lady in Black fled in horror, screaming that it would take her another two hundred years before she could again be freed.

In woods alongside the Melingriffith-Tongwynlais footpath there was once a spring known as the White Lady's Well. It was, of course, named after a ghostly White Lady who was said to haunt it. The ghost was thought to have been that of a woman who was stabbed to death nearby by her lover. Tradition had it that a stone placed in the water of the spring would turn red because of her blood. And so it would - but only, of course, because of iron oxide in the water. A second 'Ladi Wen' (White Lady) was said to haunt Radr Ford, a third the Tithe Barn which once stood near the entrance to the present day Whitchurch Hospital.

It was at the Tithe Barn too that a farm labourer by the name of Draper apparently hanged himself from a rafter in the early 19th century. According to tradition, his ghost then haunted both the barn and the road leading from there on to Tongwynlais. In around 1866 it seems that there was considerable consternation in the area after the ghost was said to have been seen on several occasions both on the road and in surrounding woods and fields. Eventually a ghost hunt was organised. The 'ghost' was caught. It turned out to be an impoverished mad woman who lived in the neighbourhood and whose wont it was to wander about the area at night, even in the most inclement weather.

That said, a member of the Lewis family who used to live at Greenmeadow in Tongwynlais (about which more in a moment) was convinced that there was a ghost haunting the barn. She described how Greenmeadow horses drawing carriages past the barn would often take fright there and then gallop out of control past their home gates as well, only coming to a halt again when they reached 'the shop in Tongwynlais owned by old Mrs. Bond', by which time they would be covered in sweat.
