Surrounded by woodland and rolling countryside and dominated by its magnificent 12th-century castle, it is a popular tourist centre attracting thousands of visitors each year. Its location makes it an excellent base for touring the Pembrokeshire National Park, the Gower Peninsula and the Brecon Beacons.
The town dates back to the 12th century when the castle was built in 1106. The town received its Royal Charter from King Henry I and was established as a borough 1115. In a field near the Castle, known as Maes Gwenllian, a battle took place in which Owain Gwynedd's sister, Prince Gwenllian, led her husband's troops into battle during his absence. Both Gwenllian and her son were put to death here either during, or shortly after, the battle. Cloth was manufactured here during the Middle Ages and tin working began in the 18th century, which continued to the early 20th century.
Economically, the service industry, including tourism, is the largest sector of the local economy, employing 65% of all workers.
