Another beautiful campus is Texas State! Right on the river, where there are always students hanging out studying or floating. First time visitors are always surprised at how pretty the campus is.
Notre Dame and Cornell
Gothic Wonderland at Duke is stunning. Princeton and Yale are also picturesque.
University of Oklahoma - I love Frank Lloyd Wright and Cherokee Gothic!
Fordham Rose Hill is lovely. There are many lists on this which you can google quickly.
Did Wright do a building at Oklahoma?
I don’t think he did, I think he just coined the term “Cherokee Gothic” on a visit there.
Florida Southern has an incredible number of Frank Lloyd Wright buildings
Duke.
Miami of Ohio is tough to beat. Indiana u.
Embry-Riddle Prescott is very beautiful (and hugely underrated IMO). It’s not your typical ornate “sculpted” campus, but the way it blends in with the natural beauty of the surrounding area is truly spectacular.
Other atypical beautiful schools:
- Cal Poly
- Northern Arizona
- Sierra Nevada College
- University of Utah
- New Mexico Tech
- University of Montana
Princeton, UVA, Duke, URichmond, Stanford, Cornell
Princeton, Washington, Baylor, Miami (Florida), USC, Pepperdine, Yale, SMU…
I love Notre Dame and University of Washington’s campuses! Santa Clara University also seems beautiful from pictures though I’ve never been in person. 
I’d say Georgetown. Visiting the beautiful Georgetown made me feel like I had just stepped into a dreamland!
More votes for Washington, Notre Dame, Georgetown and USC!
Yale, Princeton, Georgetown, Dartmouth.
Can you take a wild guess why your opinion might be unpopular?

^ This entire thread has been about opinion. I particularly liked that post you referred to because it was both supported by description and did not involve a truly ugly school.
Does not make the description of "a few hundred near-identical office buildings that have beige stucco walls and red tile roofs in an attempt to look vaguely like the Spanish Mission style’ anything more than an … opinion. Everyone is entitled to an erroneous one but not his own set of facts. A few hundreds near-identical OFFICE buildings? Really!
Fwiw, the beauty or lack thereof of a campus does not necessarily involve being a Hogwarts look-alike with Gothic architectural elements. It’s more than that as the school ought form a unified and enjoyable environment that extends to the city in which it is located. A number of remarkable schools are located in less than hospitable hoods. Think JHU, Penn, or Yale. Other schools have remarkable architecture but are paying the price of overcrowding and lack of maintenance. How great is it to marvel at the architecture of Princeton if you have to spend 4 years in a basement?
It’s all a matter of taste and expectations.
