The village of Tan-y-Groes is situated about six miles north east of Cardigan, on the A487. The first edition of the 6inch OS maps, published in 1891, shows that there was a working quarry on the eastern edge of the village - the Pwntan Quarry. When the second edition of the 6inch OS maps was published in 1906 the quarry was still open, but the fourth edition, published in 1953, labelled Pwntan Quarry as 'disused.' The first, second and fourth editions of the 6inch OS maps showed that Tan-y-Groes had a Methodists chapel and cemetery (NPRN 7167) as well as a public house called the Gogerddan Arms. There is still a public house called the Gogerddan Arms in the village, although according to its website, the building 'was built in the late 1960's as a flagship pub for Buckley's Brewery. It was considered very modern in its time; and this explains its now almost iconic shape.' The Methodist chapel had already been converted into a dwelling and was up for sale at the time of writing. Today Tan-y-Groes has a Kingdom Hall of Jehova's Witnesses, a garage, and the Emlyn Cafe. The 2017 edition of the OS map also shows that there is a post office next to the Kingdom Hall of Jehova's Witnesses.
