Carrickfergus in the 1830s
The town is situated on the north-western shore of Carrickfergus bay, or Belfast Lough, along which it extends for nearly a mile, comprising three portions, the town within the walls, and two suburbs, called respectively the Irish and the Scottish quarters; the former situated to the west, along the road leading to Belfast; and the latter to the north-east, along the road to Larne and Island Magee, and inhabited by the descendants of a colony of fishermen from Argyle and Galloway, who took refuge here from the persecutions of 1665. The town within the walls was formerly entered by four gates, of which only the remains of the North or Spittal gate now exist; of the walls there is yet a considerable portion on the north and west sides in a very perfect state. The town contains about 800 houses, built chiefly of stone and roofed with slate; several of superior character have been built within the last forty years, during which period considerable improvements have taken place.
The castle, which is in good preservation, and during the disturbances of 1798 was used as a state prison, is situated on a rock projecting boldly into the sea, by which it is surrounded on three sides at high water; this rock is 30 feet in height at its southern extremity, and declines considerably towards the land; the outer walls of the castle are adapted to the irregularities of its surface; and the entrance is defended by two semicircular towers, with a portcullis and machicolation above. In the interior are barracks for the reception of two companies of foot and a few artillerymen. The keep is a square tower 90 feet high, the lower part of which is bomb-proof, and is used as a magazine: in the third story is an apartment 40 feet long, 38 feet wide, and 26 feet high, called Fergus's dining-room. The well in this tower, anciently celebrated for its miraculous efficacy, is now nearly filled up; a quantity of old iron was taken out of it many years since, from which it may have derived its medicinal properties.
The castle was formerly governed by a constable, who had very extensive powers; the present establishment consists only of a governor and a master-gunner. Musical societies formerly existed and occasional assemblies were held in the town, but the only source of public amusement at present is a sporting club. Though formerly celebrated for its trade and commerce, this place has never been distinguished for the extent of its manufactures: the linen manufacture, which was the staple, has, within the last fifty years, been superseded by that of cotton, for which there are at present two spinning factories; and many persons are engaged in weaving checks, ginghams, and other cotton goods for the manufacturers of Belfast and Glasgow. There are also two mills for spinning linen yarn, and an extensive distillery, producing annually about 90,000 gallons of whiskey, with mills, malt-kilns, and other conveniences on an improved system; the tanning of leather, which was introduced here at an early period, is still carried on to a great extent. The vicinity affords numerous advantageous sites for the establishment of manufactories: a considerable water power is supplied by the Woodburn and Sulla-tober rivers, and by the water of Lough Morne; there are 1070 feet of waterfalls, calculated at 676-horse power, of which by far the greater part is unoccupied.
