Cadw's description

Set back slightly from the SE side of the road below Holyhead mountain, SW of Holyhead.

One of the 6 'Holy Wells' on Holy Island, Ffynnon y Wrach was often used as a source of water for residents of Holyhead. Well housing probably late C19 or early C20.

An octagonal well building with domed roof. Walls of rubble with brick angle quoins, plinth of similar materials and rendered stepped cornice under a cement rendered concrete domed roof. The cornice is broken by the cast iron lintel and jambs of the single doorway in the NW face; each with recessed panels with stressed surrounds.

Listed as a late C19 well house, of highly unusual design and construction.
