Light O' the Morning by L.T. Meade

The house, a great square pile, was roomy and spacious; it had
innumerable staircases, and long passages through which the wind
shrieked on stormy nights, and a great castellated tower at its
north end.

Audley End, Essex

Legia by Edgar Allen Poe

The room lay in a high turret of the castellated abbey, was pentagonal
in shape, and of capacious size. Occupying the whole southern face
of the pentagon was the sole window --an immense sheet of unbroken
glass from Venice --a single pane, and tinted of a leaden hue, so that
the rays of either the sun or moon, passing through it, fell with a
ghastly lustre on the objects within.

Skenfrith, Monmouthshire

A Tramp Abroad by Mark Twain

On the right bank, two or three miles below the Spectacular Ruin, we passed by a noble pile of castellated buildings overlooking the water from the crest of a lofty elevation.

Embleton Bay, Northumberland

Peveril of the Peak by Sir Walter Scott

The defeated Cavalier escaped from the field of battle, and, like a true descendant of William the Conqueror, disdaining submission, threw himself into his own castellated mansion, which was attacked and defended in a siege of that irregular kind which caused the destruction of so many baronial residences during the course of those unhappy wars.

Ashby de la Zouch Castle, Leicestershire

The Secret Chamber at Chad by Everett Evelyn-Green

Every castellated turret and twisted chimney
stood out in bold relief from the heavy background of the pine wood
behind, and the great courtyard lay white and still, lined by a
dark rim of ebon shadow.

Cragside, Northumberland
