Just a couple of descriptions of "Gothic" buildings, the need to describe aspects of the landscape as "rude" and to ensure that trees and buildings appear "coeval" is definitely important.
I know there are more identikit descriptions, so I shall add as I find them
He approached, and perceived the Gothic remains of an abbey: it stood on a kind of rude lawn, overshadowed by high and spreading trees, which seemed coeval with the building, and diffused a romantic gloom around. The greater part of the pile appeared to be sinking into ruins, and that, which had withstood the ravages of time, shewed the remaining features of the fabric more awful in decay. The lofty battlements, thickly enwreathed with ivy, were half demolished, and become the residence of birds of prey. Huge fragments of the eastern tower, which was almost demolished, lay scattered amid the high grass, that waved slowly to the breeze. “The thistle shook its lonely head; the moss whistled to the wind.”
Romance of the Forest – Ann Radcliffe, 1791

Time, however, had been less sparing, and marked it in many places with visible decay; some of the windows were dismantled from the failure of the stone work, and many of the battlements had mouldered away. It stood upon an elevated lawn, sequestered in the bosom of an extensive wood, whose mighty shades appeared coeval with itself.
