CASTLEMARTYR, 16 m. from Cork, a large manufacturing town.--See the ruins of the ancient Castle, and the seat and grounds of the Boyle family: the house itself is worth seeing, being antique and assimilating well with the richly clad wild remains of an ancient castle, whose venerable turrets in majestic ruin peep forth from the thick foliage at a short distance; add to this an extensive sheet of water, which gives life to the surrounding scenery. Let the botanical tourist pay particular attention to the flower-garden and green-houses, elegantly arranged under the taste and genius of the Countess of Shannon. Visit Ballycotton Bay, with extensive strand, good wild fowl shooting and excellent flat- and shell-fish. See there the Ch. and Castle of Ballycrenane. About 1 m. S.E. is the river Dour, which breaks out from a limestone rock, after a subterraneous course of near half a mile, and forms a small lake, where the Halcyon or Kingsfisher is found in great numbers: Charleville, 14 m. N. of Cork, on the borders of Limerick; see Charter School, Ch. and Barracks. The magnificent seat of the Earls of Orrery was burnt down in the wars of the Revolution by the Duke of Berwick after dinner, like the ancient Persepolis. CLOGHNAKILTY, 22 m. S.W. of Cork,--is seated on a shoal and dangerous bay. See the plain neat Ch. pleasingly situated, but the town is described by Miss Plumptre as poor and dirty. Dundedy or Galway Head has some curious caves worn out by the sea, also ruins of an old Castle. Iniskean, about 8 m. N., has close to it the ruins of Kinigh Ch. with remarkable round tower, a hexagon at the bottom and the upper part round, 70 feet high and 124 feet from the Ch. At Temple Bryan, 1 m. distant, are some remains of an ancient Temple; near the Ch. a stone circle with central pyramidal pillar, and two other pyramids in the immediate vicinity. At Timoleague, about 5 m. E., see ruins of O'Shaughnessy's Castle, and the extensive remains of a venerable Franciscan Abbey, 1350, with numerous tombs of Irish chieftains, Gothic cloisters, and romantic ruins of the ancient monastic apartments: see also the Holy Well.
