Kilmaoge has an ancient Ch. At Lackagh, 3 m. W., ancient cemetery with ruins of Ch. and Castle. Monasterevan, 5 m. S.W., has a modern built Ch. and Nursery for the Leinster Charter Schools: near it the venerable but beautifully repaired mansion of Moore Abbey, seat of the Marquis of Drogheda. At New Bridge, ruins of magnificent Abbey of Great Connell. Rathangan, on the banks of the canal, suffered greatly in the rebellion. LEIXLIP, 8 m. from Dublin, near Lucan, a romantic scene of wood, rocks, and water.--Near it, at Castletown, is the finest house in Ireland, built by the late Mr. Conolly: a large handsome edifice situated on an extensive lawn surrounded by fine plantations, uniting with sombre woods and artificial scenery. From hence visit also Cartown, the picturesque seat of the Duke of Leinster; Summerhill; Dangan, &c. &c. See also the Salmon leap, with magnificent old Castle delightfully seated on a rising ground overhanging the Liffey, near which is the celebrated Aqueduct of the royal canal, being 85 feet above the river, equal to the famous Roman work at Pont de Gard in France. The village is picturesquely situated on the edge of the river, near a charming wild romantic dell, where high slopes covered with wood rise on each side above the water, having paths that lead to the Cascade. See at St. Woolstan's, 2 m. S.W., ruinous towers and gateways of ancient Priory (1208). MAYNOOTH, 11 m. from Dublin, has lately become famous for its Roman Catholic College, formed to receive a great number of students. It has a large Inn and fine Market-house; also a Protestant Charter School, and near it are the ruins of an ancient Castle. Bishop's Court may be visited along with the beauties of Leixlip: it is a magnificent mansion and highly cultivated demesne of Lord Ponsonby. Celbridge, a modern built village, is highly worth notice, with fine stone bridge over the Liffey, and at the lower extremity an elegant Ch. lately erected. See extensive woollen manufactory; also at the S. end of the village, remains of a magnificent Abbey, now repaired, and converted into a habitation presenting all the external appearance of its former character, in all the gloomy grandeur of Gothic architecture. Castle Browne, not far distant, has recently been purchased for a society of Jesuits. Furnace is a beautiful seat, lately much improved, with ruins of ancient chapel in the lawn, in which is a window of painted glass of high antiquity and extreme beauty. At Oughterard, see ancient Ch. and Round Tower on summit of a hill. Prosperous is another modern creation, being founded by Colonel Brook in 1780, for a Cotton Manufactory: 1/2 m. distant from which, at a place called the Cott, is a strong sulphureous spa, richly impregnated also as a chalybeate, useful in scrophulous and cutaneous diseases.
