or Derry, the capital of the county, and the see of a bishop, stands at the bottom of Lough-Foyle. This city has a very good port, to which ships of the greatest burden have access, and a considerable trade. It will be ever famous for the gallantry and perseverance with which it defended itself in three memorable sieges, in defiance of the greatest hardships and discouragements, namely, 1st, In 1641, when the rebels could not reduce it either by fraud or force. 2dly, In 1649, when it was besieged by the Lord Ardes, and reduced almost to extremity by famine, till at last relieved by troops sent from England. 3dly, When it held out against the French and Irish from the 7th of December 1688, to the last day of July 1689, though it was neither well fortified nor provided with a garrison or stores of provision and ammunition, and hardly any attempt made to relieve it during so long a time. Though the city is 20 miles up the river, yet very large ships can come up to the quay, where there are four or five fathoms of water. It is now well fortified with a strong wall, besides outworks; and along the banks of the river are several castles and a fort. This city is of no great antiquity, having been built and planted in the reign of James I. by a colony sent by the society above mentioned. The trade of the town is very considerable, having not only a large share in the herring fishery, but sending ships also to the West Indies, New England, and Newfoundland, for which they are so advantageously situated, that a vessel bound from thence to America often arrives there before a London ship can get clear of the soundings, or arrive in the latitude of Londonderry. Though there are many shallows in Lough-Foyle, which serves it instead of a road; yet they are easily avoided. There is in the town an Infirmary, a Theatre, and a Linen-Hall. There is also a large and commodious Jail, and an elegant Court-house. The inhabitants of this city are almost all Protestants. It gave the title of earl and baron to a branch of the family of Pitt, which became extinct in 1764; but part of the title was revived in Robert Stewart, who was created Baron Londonderry. Derry in 1789. A late traveller says, "Derry is, perhaps, the cleanest, best built, and most beautifully situated town in Ireland; and excepting Cork, as convenient as any for commerce, foreign and domestic." The lake almost surrounds it; and the whole ground-plot both of it and its liberties belongs to the 12 great companies of London. The imports are flax seed, hardware, iron, timber, and West India goods. The exports are yarn, linen, salmon salted and barrelled, &c. It contains 18,500 inhabitants, and has a wooden bridge 166 feet long, which was erected in 1791. Long. 7° 5' W.; Lat. 55° 4' N.
