The size of a college or university is usually measured by the number of students enrolled at the school.
By this standard, the largest university on earth is the State University of New York, which includes colleges in about 20 cities and has an enrollment of more than 320,000 students!
The largest college building on earth, though, is in the Soviet Union, outside the city of Moscow. It is Moscow State University.
This huge structure, with one building 37 stories high (Moscow’s tallest skyscraper), contains about 40,000 rooms, more than 20 times the number of rooms in the largest hotel!
The world’s oldest university, in Fez, Morocco, has been open since the year 859!
Uhm.. actually the largest university in the world (by number of students enrolled) is the Allama Iqbal Open University with over 3 million students.
