Pentre-cwrt takes its name from the court or farmyard of Whitland’s Maenor Forion grange. According to the antiquary Edward Lhuyd, it was the abbot’s summer retreat.
Up hill from the village is the grange chapel, dedicated like most Cistercian churches to the Virgin Mary. The chapel survived the Dissolution and became a chapel of ease called Capel Mair. This suggests that there were plenty of people living on or near the grange lands by the sixteenth century. The chapel was rebuilt by the Victorians and services are still held there every Sunday.
The settlement may even be older than the grange. Inside the church are fragments of an early medieval inscribed stone which was found in the churchyard. It has an inscription in Latin and ogham (an early form of Irish writing) DECABARBALOM FILIUS BROCAGNI, ‘Cabarbalom son of Brocagnus’. These are Irish names: Brocagnus means ‘Little Badger’.
North-east of the church are two farms called Llwynyffynnon Uchaf and Isaf, Upper and Lower Wellgrove. The well is a holy well dedicated to the Virgin Mary, but there is no public access to it.
