WARRENPOINT  , a seaport and watering-

place of county Down, Ireland, the terminus of a branch of the Great Northern railway, by which it is 504 m . S.S.W. of Belfast . Pop . (1901) 1817 . It lies on the northern shore of the beautiful Carlingford Lough; behind it rise the Mourne Mountains, while across the lough are the Carlingford Hills, with Slieve Gullion . These hills afford shelter from inclement winds, and give Warrenpoint and other neighbouring watering-places on the lough a climate which renders them as popular in winter as in summer . There is a quay here where large vessels can discharge, and agricultural produce is exported . The shores of the lough are studded with country seats lying picturesquely on the well-wooded hill slopes; and nearly 3 M . E. of Warrenpoint (connected by tramway) is Rosstrevor, one of the most noted watering-places in Ireland, charmingly situated in a position open to the sea, but enclosed on the north and east .
