Two miles east of Newport, St Brynach's beautifully melancholic churchyard dates from around the 6th century, predating the 13th-century church itself. Within the graveyard is a tall Celtic cross, one of Wales' finest, decorated with interlace patterns. According to tradition, the first cuckoo that sings each year in Pembrokeshire does so from atop this cross on St Brynach's Day (7 April). The churchyard's gloomy alley of yew trees is estimated to be upwards of six centuries old.
Inside the church, the Maglocunus Stone in the south transept dates from around the 5th century, and is one of the few carved stones that bears an inscription in both Latin and Ogham. Stones like these were important tools for deciphering the meaning of the ancient Celtic script.
Up on the wooded hill behind the church you'll find a pilgrims' cross and the scant remains of Nevern Castle, originally a Welsh stronghold, then rebuilt by the Normans and eventually destroyed by the Welsh in 1195.
