"The scenery is highly picturesque; and from the hills, which surround the village, are obtained some fine prospects, extending over the fertile and beautiful Vale of Clwyd, and embracing a view of the Irish Sea, and the summit of Snowdon, with the adjacent mountains. The elevated parts of the parish are thought to abound with mineral treasures; and iron stone has been found, and a forge and foundry set up in the neighbourhood for the working of it."
[From Handbook for the Vale of Clwyd , William Davis, 1856]
Cwm is one of the ancient parishes of Flintshire, comprising the two townships of Uwchllan and Isllan. It remained unaffected by the widespread creation of new parishes during the Victorian era.
