Creagan an Fhithich looks out over Loch Oich in the Great Glen, but it's not so much the rock that's the important factor, but that it was the site of Invergarry castle, the seat of the Chiefs of the MacDonells of Glengarry.
The castle had a turbulent history, being destroyed and rebuilt several times after attacks by Scottish Covenanters, Cromwell's troops under General Monk and Loyalist/Hanoverian troops. It was finally destroyed in 1750 by Loyalist troops, but the ruins remain.
Of particular interest to this forum is that after the first Jacobite rebellion the castle was forfeited and occupied until 1731, when Glengarry regained it. During the time of the occupation one of the authorities of the hostile army forces was the English entrepreneur Thomas Rawlinson, who took over the castle and built an iron works nearby. He is also credited by many for inventing the modern kilt on the Glengarry site around 1725. This claim was made in The Edinburgh Magazine in March 1785, but referred to an earlier letter of 1768 by Ivan Baillie of Aberiachan.

"an" means "the" It shouldn't be tacked on, and then repeated, but it this case, creagan is the plural of creag. So in one version, it is the The Raven's Rocks, and in the other, The Raven's Rock (or Cliff)
