Gullion definition

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.

The situation of the town is striking, the Newry Mountains and Slieve Gullion on the west, and the Mourne Mountains on the east, enclosing the narrow valley in which it lies.

The general surface of the county is gently undulating and pleasantly diversified; but in the northern extremity, on the borders of Lough Neagh, there is a considerable tract of low, marshy land, and the southern border of the county is occupied by a barren range of hills, the highest of which, Slieve Gullion, attains an elevation of 1893 ft.

It is penetrated by far younger intrusive masses at Slieve Gullion and Forkill.
