KELLS, 12 m. N.W. of Trim, being pleasantly seated on the Blackwater, forms a good station for the western part of the county. See the Market-house on the site of an ancient Castle; also curious stone Cross, much decayed, but decorated very richly with figures of men, beasts, flowers, &c. Here is a remarkable round tower, 90 feet in height and 16 in diameter, with walls 3 feet in thickness. It is close to the Church, at an opposite corner of which, and detached, stands a square tower with a spire, the remains of an ancient edifice now destroyed. At the back of the town there is another small round tower; also a small stone building arched with flags, called Columkill's Cell, supposed to be the first Christian oratory erected here. The Ch. is modern; and in the cemetery a curious sculptured cross. See the noble mansion of the Marquis of Headfort in its vicinity, and its extensive grounds. NAVAN, 7 m. N.E. of Trim, stands very pleasantly on the Boyne, and has a considerable trade. Its vicinity has much picturesque scenery for the pedestrian tourist. See the Tholsel; and the remains of several ancient tombs in the Abbey cemetery, adorned with sculpture. The beautiful episcopal palace of Ardbraccan, 2 m. W., displaying simplicity of design with accuracy of execution, is built of a remarkable limestone with a very fine grain, found in the immediate vicinity. The quarry is worth visiting. The limestone is capable of being worked into any form for building; is susceptible of a fine polish; and though white when it comes from the chisel, acquires a sober grayish tint after exposure to the air. Its strata are horizontal and of various degrees of thickness, from four inches to two feet; and columns have been raised and worked of 9 or 10 feet in length, and from 15 to 18 inches in diameter. A short distance from Navan, close to the village of Donoghmore, and standing on an eminence near the road leading to Slieve, is a round tower adorned with sculptures of the Crucifixion over the doorway. It is not in very good preservation; and the ancient Ch. attached to it is totally in ruins. Dunmore Castle is a building of very early date, but almost new built as a castellated house at the close of the 17th century, and now presenting a curious specimen of those turbulent times in its lofty towers and heavy walls, diversified only by a few windows close to the battlements. In the vicinity of Dunshaghlen see Dunsany and Killeen Castles, mansions of Lords Dunsany and Fingal. Near the latter examine the Ch. and sepulchral antiquities. The tourist who is partial to extensive prospects, may visit the Hill of Screen, on whose summit is a Ch., presenting from the battlements of the ruined belfry a most delightful view over a richly cultivated country. The edifice itself is in a state of dilapidation, except part of a chapel fitted up for divine service; but the antiquary may amuse himself with examining
