The churches are all of small dimensions--never more than sixty feet in length--at the eastern end of which is not unfrequently a chancel in which the altar was placed. Between the nave of the church and the chancel was the chancel arch of a semicircular form, a very beautiful specimen of which exists in the Protestant cathedral of Tuam. These temples, very imperfectly lighted by small windows splaying inwards, do not appear to have ever been glazed. The chancel had usually two or three windows--one of which is always in the centre of the east end, with another in the south wall, another in the south wall of the nave, sometimes, though rarely, two in number. The windows are frequently triangular-headed, but more usually arched semicircularly, whilst the doorway is almost universally covered by a horizontal lintel consisting of a single stone. In all cases the sides of the doorways incline like the doorways in the old Cyclopean buildings, to which they bear a striking resemblance. The smaller churches were usually roofed with stone, whilst the larger ones were roofed with wood covered with thatch. The wells are carefully preserved, the scarcity of water rendering the possession of a well almost as precious to them as to the Eastern shepherds in the days of Rebecca. The Aran churches, it must be admitted, have little in them to interest the mind or captivate the senses; nevertheless, in their symmetrical simplicity, their dimly lighted naves, in the total absence of everything that could distract attention, there is an expression of fitness for their purpose too often wanting in modern temples of the highest pretensions.
