Peillac Way is so called as St Clears is twinned with Peillac in Brittany, France. The towns were officially twinned in 1997. There were strong connections with the Normans as can be evidenced from the establishment of the Castle, the Priory and the Township in the 12th Century.
Peillac Way continues south and passes through one of St Clears' historic river meadows. These meadows were formerly part of the extensive common land enjoyed by the Burgesses of St Clears since the 12th or 13th Century. Until the early 19th Century, six riverside meadows remained as part of this common land including Yr Island, Werglo Lloy, Portreeves Meadow, Prymus, Werglo Wharrey, and Gors Fawr/Gors Fach. Yr Island was the low lying land that can be seen on the western side of the footpath. This may have originally been part of Werglo Lloy and may have been so named after it was separated from it by a change in the course of the river.
