The High Street of Oxford, a good example of a university town. There is no main campus, rather university buildings are around the city between shops, for example those at centre right of the picture.
A college town or university town is a place (often a town or city) that has a college or university that is an important part of that place. The university may be a very big part of the place's economy and culture, and there may be a lot of students living there. Many residents may work for the university, the university may be the biggest employer, and many businesses may work with the university.
