Cnoc Bhreanail Brandon Hill

Brandon Hill is the highest mountain in County Kilkenny. It has an elevation of 515 m (1,690 ft). It is situated 4 kilometers South-South-West of Graignamanagh, 7 kilometers east of Inistioge and 11 kilometers east of Thomastown, in the south of County Kilkenny. Brandon Hill is in the barony of Gowran and in the province of Leinster. The village of Graignamanagh is at the base of the hill.

It is the termination of the chain of granitic mountains that raise from the shores of Dublin bay. The base of Brandon Hill on the side of the River Barrow and the hill running to Graig is composed of schist rock. This blackish siliceous schistus, sometimes containing grains of quartz and when it is broken it has a shivery texture and is hard enough to scratch glass. There are a few beds of marble and limestone gravel near the foot of the mountain.
