Next, three miles out, are the ruins of Aghadoe castle and church. All that remains are the fragments of a tower thirty or forty feet in height. Of its history, or the date of its foundation, no records are extant. The church is a fine ruin, and shows the remains of a long low building, consisting of two chapels, joined at their rear ends. The easterly chapel is in the Gothic style, bearing date A. D. 1158, and is dedicated to the Holy Trinity. Full seven hundred years are gone, more than a third of the Christian era, since that stone pile was placed where it is. The other chapel is older yet, of a rude, Romanesque architecture, and was built under the patronage of St. Finian. The two are separated by a solid wall, through which there was once a communication, closed up long before the vacating and destruction of the building. The roof and woodwork being gone, nothing but stone remains. The two chapels, extending to the east and west, are eighty feet long and twenty feet wide. Continuing our ride a mile farther, we turn to the left, and pass the Aghadoe House,--a fine and well-kept estate, the residence of the Dowager Lady Headley. Next, we turn sharp to the right, and are at the estate of James O'Connell, Esq., brother of the late distinguished agitator, Daniel O'Connell. Continuing, we pass the Killalee House, and the ruins of its church. Six and a half miles now from Killarney, we have on our left, the elegant estate of Beaufort House. We cross the little River Laune, which is filled with surplus water from the small, or upper lake, and here appears to view Dunloe Castle, the seat of Daniel Mahoney, Esq. The building has a modern look, and was originally the residence of the powerful and noted O'Sullivan Mor. We must not fail to notice the Cave of Dunloe. It is situated in a field some distance off, is of great antiquity, and was discovered in 1838. It contains peculiar stones, which are presumed to belong to an ancient Irish library; and, strange to say, the books are the large stones composing the roof. Their angles contain the writings, which are simple, short, vertical lines, arranged, tally-like, above and below a horizontal one. Special numbers or combinations of these lines designate letters. It is the Ogham alphabet. We are now near the cottage of the celebrated Kate Kearney, whom Moore has immortalized in his "Sweet Innisfallen,"-- "Kate Kearney, Who lives on the banks of Killarney."
