The town was founded at the end of the C12th by Norman William FitzMartin. Although the castle he built has been in ruins since at least the C17th, it is impressive due to its site and views and a converted house incorporating the walls of the castle is still inhabited.
The town today has a population of some 1,100; Newport Sands is a mile long, wide, flat, dune-backed beach; Newport and Newport Parrog were designated as a conservation area by the Pembrokeshire Coast National Park in 1999.
The Norman church of St Brynach at Nevern (north-east of Newport) is on the site of an important C6th ecclesiastical centre. Except for the castellated tower, most of the original Norman structure of the present building has been rebuilt. The Nevern Cross on the south side of the church dates from the C10th or early C11th century. It consists of two sections fitted together cut from the local stone and has classic braided decorations and inscriptions; nearby is the Vitalianus Stone, dating from around 500 AD.
Castell Henllys is one of many prehistoric promontory forts in the Pembrokeshire National Park dating to around 600 BC. Archaeologists have been excavating here for over twenty years and thatched Iron Age buildings have been reconstructed on their original foundations. The site provides a unique combination of Scheduled Ancient Monument, archaeological excavation and experimental archaeology.
Pentre Ifan Cromlech, located south-east of Newport with some spectacular views over the north Pembrokeshire countryside, is a Neolithic site of a chambered cairn thought to date from 3500BC.
Excavations have revealed the three standing stones that support the capstone which is said to weigh around 16 tons and points at the River Nevern. To the east of Newport in the village of Eglwyswrw is the Dyfed Shire Horse Farm and throughout the summer it has a daily working horse harness demonstration, ploughing with working horses, a farrier at work and falconry demonstrations.
