Holyhead Mountain is the highest point in Anglesey, at 216m (710 ft.). From the rocky height you can see the Isle of Man, the Mourne Mountains in Ireland, Snowdonia, and Cumbria on a clear day. The summit is the site of an ancient hill fort and the ruins of an Irish settlement from the 2nd to the 4th century A.D. The towering cliffs of North and South Stack are home to thousands of sea birds, and gray seals breed in the caves below. At the southern point of the mountain, South Stack is an automatic lighthouse built in 1808. It's 27m (91 ft.) high (60m/197 ft. above mean high water) and can be seen for 32km (20 miles). It's noted for its antique walls, its strategic position, and a state-of-the-art light beam. Open March through September daily from 8am to 6pm, charging £4 ($6.40) for adults or £3 ($4.80) for children under age 16. For information, contact the Royal Society for the Protection of Birds at tel. 01407/763043.
On Friday and Saturday, general markets are held in Holyhead.
St. Cybi's Church, Market Street (no phone), near the town center, is on the site of a 6th-century church; a Roman fort from the 3rd century also stood here. The site is open daily from 8am to 6pm; admission is free. For information, contact the tourist office.
