Quadrangle
From Zeugma
"In architecture, a quadrangle is a space or courtyard, usually square or rectangular in plan, the sides of which are entirely or mainly occupied by parts of a large building. The word is probably most closely associated with college or university campus architecture, but quadrangles may be found in other buildings such as palaces. Most quadrangles are open air, while a few have been glazed over often to provide additional space for social meeting areas or coffee shops for students." Wikipedia
The quadrangles in That Hideous Strength are found in Bragdon Wood.
"First you went through the Newton quadrangle which is dry and gravelly; florid, but beautiful, Gregorian buildings look down upon it. Next you must enter a cool tunnel-like passage, nearly dark at midday unless either the door into Hall should be open on your right or the buttery hatch on your left, giving you a glimpse of indoor daylight falling on panels, and a whiff of the smell of fresh bread. When you emerged from this tunnel you would find yourself in the medieval College: in the cloister of the much smaller quadrangle called Republic. The grass here looks very green after the aridity of Newton and the very stone of the buttresses that rise from it gives the impression of being soft and alive. Chapel is not far off: the hoarse, heavy noise of the works of a great and old clock comes to you from somewhere overhead. You went along this cloister, past slabs and urns and busts that commemorate dead Bractonians, and then down shallow steps into the full daylight of the quadrangle called Lady Alice. The buildings to your left and right were seventeenth-century work: humble, almost domestic in character, with dormer windows, mossy and grey-tiled." That Hideous Strenght, pg 20
In this description, the quadrangles seem to be almost naturally formed glens within the wood, even though they are clearly formed from the decaying buildings around them. The third quadrangle, Lady Alice, could be representative of the area that Excalibur was allegedly found by King Arthur in the legend told in The Once and Future King as The Sword and the Stone.
It is also mentioned near the end of the novel when Curry indicates that he will be the second founder of Bracton College and will erect a statue of himself in the quadrangle.
