YOUGHAL, a parliamentary borough and seaport town of Ireland, Munster, Cork County, 28 miles E. from Cork, and 157 S.W. from Dublin. It is situated on the acclivity of a hill on the W. side of the estuary of the Blackwater, over which there is a wooden bridge 1787 feet long. The harbour is safe and commodious but has a bar at its mouth with only 5 feet water at low tides and 13 at high-water of neap tides. A harbour lighthouse has recently been erected at the south end of the town, and a fort is to be erected at the entrance to the harbour. The port is a dependency of that of Cork, and the exports are chiefly grain, flour, and provisions. The town is to some extent visited in summer for sea-bathing, for which it is well adapted. The salmon-fishery of the Blackwater is extensive. The chief manufactures are coarse earthenware and bricks. The principal public building in the town is the parish church, a large Gothic edifice, which formerly belonged to a monastery, of which some more remains still exist. The other public buildings are a chapel of ease, a Roman Catholic chapel, a convent, Independent Methodist and Quaker meeting-houses, fever hospital and dispensary, town-house, prison, barracks, &c. Sir Walter Raleigh was at one time mayor of this town, and according to tradition the first potatoes brought by him from America were planted here. Myrtle Grove, the house occupied by him, is still preserved in nearly its original state. The borough returns one member to parliament. Pop. (1851) 7410.
