a town and cape of the isle of Anglesea in Wales, and in the Irish channel, where people usually embark for Dublin, there being three packet-boats that sail for that city every Monday, Wednesday, and Friday, wind and weather permitting. It is 276 miles from London, and has a very convenient harbour for the northern trade, when taken short by contrary winds. It is situated near the extremity of the isle, and is joined to the north-west part of it by a stone bridge of one arch. It has a small market on Saturdays. The parish is about five or six miles long, and two or three broad, bounded nearly by the sea. The church stands above the harbour, within an old quadrangular fortification, with a bastion at each corner built about 450. On a mountain near it is another old fortification called Turris Munimentum, which is an old stone wall without mortar, and in its centre is a small turret, and contains a well of water. Holyhead was frequently formerly visited by Irish rovers, and was defended as a place of consequence. There are several remains of old fortifications and Druidical antiquities in its neighbourhood, as well as chapels of religious worship. The parish church of Holyhead was built in the reign of Edward III. and is in the form of a cross, with a porch and steeple very antique. There was an old chapel near the church, now converted into a school-house. A salt-house was erected on an island in the harbour in queen Anne's Holyhead reign, but it is now in ruins. The town is little more than a fishing town, rendered considerable by being the place of passage to Ireland. It has three good inns. The passage hence to Ireland is in general about twelve hours. There is no fresh water here except from rain, nor any bread sold but what comes from Ireland. A bath and assembly-room were erected here in 1770. Under the mountains that overhang the town is a large cavern in the rock, supported by natural pillars, called the Parliament-house, accessible only by boats, and the tide runs into it. If this harbour was properly repaired, and warehouses built, it would be very convenient for the Irish to import such of their goods as pay English duty, it being but a few hours sail from Dublin. Besides, the Dublin merchants might come over with the packets to see their goods landed. The commodities are, butter, cheese, bacon, wild-fowl, lobsters, crabs, oysters, razor-fish, shrimps, herrings, cod-fish, whitings, whiting-pollacks, cole-fish, sea-trenches, turbot, soles, flounders, rays, and plenty of other fish. On the rocks the herb grows of which they make kelp, a fixed salt used in making glass, and in alum works. In the neighbourhood there is a large vein of white fuller's earth and another of yellow, which might be useful to fullers. On the isle of Skerries, nine miles to the north, is a light-house, which may be seen 24 miles off. Large flocks of puffins are often seen here; they all come in one night, and depart in the same manner.
