THE HOWTH LIGHTHOUSE.
The bold and nearly insulated promontory called the Hill of Howth, which forms the north-eastern terminus of the Bay of Dublin, would in itself supply abundant materials for a topographical volume—and a most interesting work it might be made. For the geologist, botanist, and naturalist, it has an abundant store of attractions, while its various ancient monuments of every class and age, from the regal fortress, the sepulchral cairn, and the cromleac of Pagan times, to the early Christian oratory, the abbey and the baronial hall of later years, would supply an equally ample stock of materials for the antiquary and the historian. With all, or most of these features, we propose to make our readers somewhat familiar in our future numbers; but our present purpose is only to give some account of one of its most recently erected structures—the singularly picturesque and beautiful lighthouse, which we have attempted to depict in our prefixed illustration.
The Baily lighthouse, as it is popularly called, is situated at the eastern extremity of Howth, on a nearly perpendicular rock, whose vertex is elevated one hundred and ten feet above high-water mark. This rock, which is nearly insulated, is the terminus of a long and narrow peninsula of still higher altitude, which stretches out into the sea from the eastern end of the promontory, and whose cliffs are equally precipitous on both sides, so that the most striking and romantic views of the lighthouse can be had from various points, in some commanding the horizon-bound sea, and in others the Bay of Dublin, with all its delightful sceneries of wooded country and mountain ranges. The view which we have chosen for our illustration is taken from the northern side of this peninsula, that presented from the other side having been already published in several popular works; but we trust that this view will not be deemed less striking or picturesque; and we are of opinion that a more romantic subject of its kind is not to be found in the empire.
The lighthouse is itself an object of great interest and beauty, and is constructed according to the most approved models of modern times. Its form is that of a frustrated cone, supporting a lantern which exhibits a fixed bright light. The illumination, according to the system now generally adopted by the Trinity-house, is produced by a set of reflectors ground to the parabolic form, in the foci of which twenty large oil lamps are placed: an outer gallery, lightly but securely railed, surrounds the dome. Connected with the building on its east side, there is a large room, which opens by folding doors on a platform, and where an excellent telescope is kept, by means of which the shoals which obstruct the entrance to the bay may be distinctly observed—namely, the great Kish, and the Bennet and Burford banks, which are links of the chain extending along the Wicklow and Wexford coasts, and called the Irish grounds. These, though not visible, are distinctly marked in stormy weather by the surf, which breaks over them with uncommon violence, and form a dangerous obstruction to the approach to the bay.
The Baily lighthouse was erected by the Ballast Board of Dublin in 1814, previous to which time the Howth light, as it was commonly called, stood on a hill considerably more to the north, and at an elevation of more than three hundred feet above sea level. This circumstance of its great elevation, led, however, to its being abandoned, and the erection of the Baily lighthouse in its place, as it was found to be frequently involved in clouds and mist, while lower stations were clear and well defined.
The Baily lighthouse is a spot of no less antiquarian than picturesque interest. Its name, which is cognate with the Latin ballium, is derived from an ancient circular stone fortress which encircled the apex of the rock, and of which considerable remains existed previous to the erection of the present buildings. This great keep was fortified by three earthen walls, with deep intervening ditches placed at the entrance to the narrow peninsula, and by extending from one side of it to the other, cut it off completely from the promontory. These works still remain, though in a very ruinous state; yet they are sufficiently distinct to mark their purpose, and to convey a good idea of the style of military defensive works in use in extremely remote times. They will be found marked on the Ordnance map.
