Kearsley's Traveller's Entertaining Guide Through Great Britain (1803)
Holyhead is a cape of the isle of Angle-sea, where people usually embark for Dublin. From this place packet-boats sail as the wind permits. The church stands above the harbour, with an old quadrangular fortification, with a bastion at each corner, built about 450. On another mountain stands an old fortification , called "Turris Munimentum" , which is an old stone wall without mortar and in its centre is a small turret. There are several remains of old fortifications and druidical antiquities in this neighbourhood, as well as chapels of religious worship. The parish church was an old chapel near the church, now converted to a school-house. A salt-house was erected on an island in the harbour in queen Anne's reign, but is now in ruins. The passage hence to Ireland is, in general, about 12 hours. A bath and assembly room were erected here in 1770. Under the mountains that over hang 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. On the rocks the herb grows of which they make kelp, a fixed salt used in making glass, and in alum works.
