HOLYWELL, a town of North Wales, in the county of Flint. It is a place of great note, for the well of St. Winnifrid, who is reputed a virgin martyr; and it is much frequented by people that come to bathe in it, as well as by popish pilgrims out of devotion. The spring gushes forth with such impetuosity, that at a small distance it turns several mills. Over the spring is a chapel built upon pillars, and on the windows are painted the history of St. Winnifrid's life. There is a moss about the well, which some foolishly imagine to be St. Winnifrid's hair. W. Long. 3. 15. N. Lat. 54. 23.
