Newport is a very popular destination with tourists. It is a small town with a good stretch of sand and one of the best beaches in North Pembrokeshire. Traditionally a fishing community and a thriving port, Newport was also noted for ship building and the export of herrings. The main industry today is that of tourism. The estuary has silted up and only small pleasure boats now use this once popular port. The town has its own castle wich was built in the 13th century. In 1859 the gatehouse and one of the towers were converted into a home and the castle remains in private ownership. It is not open to the public. Newport is well known for its nearby famous site of Pentre Ifan which is just 3 miles away and a Neolithic chambered tomb with three stones supporting a huge rock suspended over them.
