Buildings 41, 42, and 43, built in 1933, are connected together and form a complex called Group 4, or more commonly, "The Quad". 41 and 43 are the same shape, symmetrical, and are built in such a way to allow the most light into all three buildings. They were used for geriatric care, and have tower-like solariums rising from the corners.

Building 42 is an X-shaped building that was centrally connected to the other two by it's four outermost points, and held four floors of kitchens and dining halls. The enclosures formed by 42 created two large courtyards in between the buildings, allowing sunlight to reach all of the wards.

It's fun to get lost in the Quad, I've spent much time wandering around it's halls. It isn't too vandalized, but one of the basement rooms was torched sometime around Christmas 2003. Luckily, the lack of flammable objects prevented the whole place from going up. A beautiful complex, Group 1, suffered that fate when it was burned to the ground in the 70's.
