Llanwnda Well is situated in ‘an area of woodland and thick vegetation at the edge of a lawned area’ approximately 60m south west of Llanwnda Church (NPRN 308468). It appears on historic and modern editions of the Ordnance Survey maps. According to Paul Davis the well ‘It appears to have been recently restored and is signposted as Ffynnon Wnda holy well.’

Dyfed Archaeological Trust visited the site as part of the Cadw Holy Wells project in 2011. They describe: ‘A stone chamber constructed over a stone lined "leat-like" stream. It appears to be a covered well consisting of a large capping stone, measuring approximately 1.5m x 0.8m and 0.35m thick, supported at its northeast corner by a large cubic boulder and elsewhere by a 1.40m high drystone wall. The well is open at its north side where the water flows out, whilst on its east side it is also open where there is a kerb stone or step down into the water filled chamber. Although this monument has a capstone covering a chamber and can also be described as cist-like it is most definitely not prehistoric, at least in its present form. Further research is required, for example, could there be an ecclesiastical association? St. Gwyndaf's Church dates to beyond the 8th century: Gwyndaf Hen was a 6th century Breton who traditionally founded the church in Llanwnda and consecrated a well - Ffynnon Wnda. The well and church were major resting places on the pilgrim road to St. David's, particularly for those arriving by boat from Ireland.’
