Ffynnon Gwenfai

A rectangular drystone structure of 3 chambers set almost completely below the level of the surrounding moorland and lying in an E-W orientation. The square eastern chamber is entered by 3 descending steps at the E end and has stone seats across each corner. To the west end is the rectangular well chamber, divided from the eastern chamber by a drystone wall with a narrow opening at the centre. The well chamber has a stone seat either side contrived in small 'apsidal' recesses; the well itself a rectangular trough with a single step down into the well and below the level of the water. Both chambers have stone flag floors. The outer chamber to the W end is divided from the well chamber by a thick drystone wall; reached by 6 descending stone steps either side, the well itself divided from the inner well by a thick stone slab with circular grooves cut into its upper and lower edges to allow water to flow from the inner to outer wells. At the W end a stone slab pierced with a hole allows water to be contained in the outer well; outflow is along a paved channel to the W leading to the cliff edge.
