The Kangaroo by D.H Lawrence

Richard watched the Observatory go by: then the Circular Quay, with all its ferry-wharves, and a Nippon steamer lying at her berth, and a well-known, big buff and black P. and O. boat at the P. and O. wharf, looking so like India. Then that was gone too, and the Governor's Palace, and the castellated Conservatorium of Music on its hill, where Richard had first seen Jack - the Palace Gardens, and the blue inlet where the Australian "Fleet" lay comfortably rusting.

Circular Quay, Sydney

Mrs. General Talboys by Anthony Trollope

I know no castellated old tumble-down residence in Italy more picturesque than this baronial adjunct to the old Roman tomb, or which better tallies with the ideas engendered within our minds by Mrs. Radcliffe and the Mysteries of Udolpho.

Housesteads Fort, Northumblerland

Contrary Mary by Temple Bailey

A later and less restrained taste had aimed at a
castellated effect, and certain peaks and turrets had been added.

The Two Paths by John Ruskin

The solitary peel-house is hardly discernible by the windings of the stream; the roofless
aisle of the priory is lost among the enclosures of the village; and
the capital city of the Highlands, Inverness, placed where it might
ennoble one of the sweetest landscapes, and by the shore of one of the
loveliest estuaries in the world;--placed between the crests of the
Grampians and the flowing of the Moray Firth, as if it were a jewel
clasping the folds of the mountains to the blue zone of the sea,--is
only distinguishable from a distance by one architectural feature, and
exalts all the surrounding landscape by no other associations than
those which can be connected with its modern castellated gaol.
