Llanfrynach is a village situated near the river Nant Menasgin. It comprises several substantial farms, rows of terraced cottages, a public house and Baptist chapel. The medieval parish church, largely rebuilt in the later 19th century, is dedicated to the local early medieval saint Brynach. It lies within a very large curvilinear churchyard and is associated with a pre-Conquest cross slab of the 10th/11th century. Current and previous settlement is centred on the church (Nprn301740).
