[Illustration: Doorway in Killiney Church, Co. Dublin.] [Illustration: Pointed Doorway in Killiney Church.] _Killiney Church._--The Church of Killiney, situated near the village of the same name, at a distance of about nine miles from Dublin, will be found particularly interesting to the student of Irish church architecture. The length of the interior is 35 feet; the nave measures but 12 feet 8 inches, and the chancel 9 feet 6 inches in breadth. The church originally consisted of a simple nave and choir, lighted in the usual manner, and connected by a semicircular arch; but, at a period long subsequent to its original foundation, an addition, the architecture of which it will be well to compare with that of the more ancient building, has been made on the northern side. The original doorway, which, as usual, is placed in the centre of the west gable, is remarkable from having a cross sculptured on the under part of its lintel. It measures in height 6 feet and 1 inch; in breadth at the top 2 feet; and at the bottom 2 feet 4 inches. The next feature to be noticed is the choir arch. This, which may be looked upon as a most characteristic example of its class, measures in breadth, where the arch begins to spring, 4 feet 7 inches, and at the base 4 feet 10½ inches; its height is only 6½ feet. The chancel windows display the inclined sides so indicative of antiquity when found in Irish ecclesiastical remains; but, with the exception of that facing the east, they are in a state of great dilapidation. The east window is square-headed both within and without, and exhibits the usual splay. The comparatively modern addition on the north side of the nave, which appears to have been erected as a kind of aisle, is connected with the original church by several openings broken through the north side wall. It will be well to compare its architectural features with those of the older structure. The Pointed doorway offers a striking contrast to that in the west gable; and its east window is equally different from that in the ancient chancel, being larger, and chamfered upon the exterior. The fact of a semicircular arch-head being cut out of a single stone is of itself no proof of high antiquity, as it occurs in many comparatively late structures in Ireland; and in England there is to be seen in the Perpendicular church of Kirkthorpe, near Wakefield, a door-head that exhibits this mode of construction. * * * * *
