With a population of just under 12,000 Welsh souls, Holyhead is the largest town on the island of Anglesey. This unassuming seaside town has a number of interesting attractions, including a maritime museum and a 4th-century Roman fort, and is known for its excellent fishing, golfing and sailing. An invigorating hike to the South Stack Lighthouse is rewarded with panoramic vistas of the Welsh coastline and across the Irish Sea. Venture east into the countryside to explore castles and fortifications collectively designated a UNESCO World Heritage site and considered to be the finest examples of military architecture from the era of King Edward I in the 13th and 14th centuries. The imposing fortresses of Beaumaris, Caernarfon and Conwy all exhibit the signature style of the king’s architect James of St. George, the greatest military engineer of his time.
