Pill priory was founded by Adam de la Roche in the late 12th Century as a daughter house of St Dogmaels Abbey and was established by monks of the Tironensian order. Pill was a small priory, home to only five monks in 1534AD, and a mere four by the time of the dissolution in 1536AD.
Today, the most obvious surviving sign of the priory is the chancel arch and the broken north transept arch, which stand inside private grounds while being visible from the road. Other elements are incorporated into the Priory Inn pub and the adjacent privcate residence also named Pill Priory.
I stumbled across this site entirely by chance on the way back to England from a stay in Pembrokeshire. It was fantastic to discover a ruin completely off the beaten track that I'd never heard of and that doesn't feature in any literature or guides that I've ever seen. It's rare to be surprised these days, so finding an unkown ruin with a fantastic, unspoiled little pub attached in the middle of nowhere was a real treat. There's not much to see, but I'd defintely recommend stopping by for a pint if you find yourself in the area on a sunny day.
