Journey across Anglesey to the ruins of magnificent Beaumaris Castle, a partly unfinished castle built by Edward I in his Welsh campaign, now a UNESCO World Heritage Site. Your half-day adventure includes independent exploration of the almost perfect symmetry of its architectural design. Begin with a scenic drive across Anglesey to the Menai Strait, past Llanfair PG, the town with a 56-letter name, and on to the seaside resort of Beaumaris, located on the eastern end of the island. Here, discover the last of the eight great fortresses known as the Ring of Iron. Construction on Beaumaris was begun in 1295 but never completed. Considered technically perfect and completely state of the art in 13th-century times, the castle features four lines of defense in the form of concentric, overlapping 'walls within walls.' Continue with a stroll through the seaside town with charming streets and quaint cottages painted in candy colors. A relaxed drive brings you back to port.
