Love Among the Ruins by Warwick Deeping

Fulviac's lair lay deep within the waving wilderness of pines. Above the spires of the forest, a massive barrier of rock thrust up its rugged bartisans into the blue. East and west it stretched a mile or more, concavitated towards the north, and standing like a huge breakwater amid the sea of boughs.

The rocky plateau above was peopled by pines and rowans, thatched also with a wild tangle of briar, whin, and heather. Crannies cleft into it; caves tunnelled its massive bosom; innumerable minarets of stone mingled with the wind-wracked trees. The cliffs rose like the walls of a castle donjon from the forest floor, studded with dwarf trees, bearded with ferns and grass. The plateau was inaccessible from the forest save by a thin rocky track, where the western slope of the cliff tailed off to merge into the trees.
