Holyhead is familiar to every reader as the favourite point of rendezvous for all who are on their way to the Irish capital. By the admirable arrangements of the Post-office, and the sure and swift-sailing packets that are here in regular attendance, a passage across the Channel is now a matter of as much certainty, as to time, as that of the mail from London. The perfect order and the surprising expedition with which passengers and despatches may thus be forwarded to and from Dublin are the general theme of admiration amongst foreigners, and a means of vast accommodation to our own commercial houses. During a long series of years the improvement of Holyhead has engaged the special attention of Government; every suggestion, entitled to the approbation of skilful and experienced engineers, has been liberally carried into effect: so that in the present day it seems hardly possible that any packet-station can offer greater facilities for all the purposes of Government, or for the interests of social and commercial intercourse, than Holyhead. The steam-vessels which carry the daily mails are of the best possible construction, commanded by experienced naval officers, and affording excellent accommodation for the passengers who are constantly passing to and fro between the British and Irish shores. The harbour of Holyhead is shaped by the natural cliffs which overhang the sea, on the verge of which stand the ancient sanctuary of the place and its cemetery. The foundation of this church--originally a small monastery--dates from the close of the fourth century: it was long afterwards remodelled into a college of presbyters by one of the Lords of Anglesey; and, after undergoing many alterations suitable to the varying taste of the ages through which it has passed, it assumed its present appearance--that of an embattled edifice built in the shape of a cross. Under the Head--the mountain from which the harbour takes its name, and which overshadows the town--are two rocky eminences nearly opposite the church, both of which are crowned with ruins which carry the mind far back among the bright days of Cambrian independence. In the rock is a wide and lofty cavern, supported by natural columns, on which tradition has conferred the title of the Parliament-house; and it is not to be denied that patriotic legislators have been often worse accommodated. This curiosity requires to be visited in a boat. On the highest point stands an uncemented circular stone wall, about ten feet in circumference, which is conjectured to have served as a _pharos_ in ancient times; for this coast has a perilous celebrity attached to it, and no vessel could safely approach the haven by night without a warning signal of this kind.
