The Middlebury College look: quiet elegance marked by lots of symmetry and limestone and marble, as shown in the building above (get a full tour of campus buildings here). The Mead Memorial Chapel below, which sits on the highest point of the campus is more of a mixture; here’s part of what this site here has to say about it:
The style of architecture was a matter of controversy, which ended in compromise. The floor plan follows the New England meeting-house style, with the door at the front end. The façade is a Greek Revival temple colonnade of marble; the doors and the windows in the marble sides are Georgian; the spire is Federal. The interior is a tasteful Georgian- inspired panelled sanctuary in stained wood.
The building known as Le Château, however, is one of a completely different mold. Of course it houses the French department but serves other purposes as well, including giving this almost magically serene campus a touch of the fantastical (read more about it here).
