I don't like clubbing - good, because there's two clubs here - one on campus, which is pretty quiet (except inside, of course), and one right over the other side of town.
I like traditional pubs serving proper beer - Then you are absolutely spoiled for choice. Canterbury is pub heaven. Check out Simple Simon's and Casey's.
I enjoy the countryside - the unis isn't technically in the city - it's up on a hill, overlooking the centre and Cathedral. The countryside almost surrounds the campus, and there are some lovely walks nearby.
I like wide open green spaces - the entire University, as said above, is set in acres of park land!
I like historical buildings and architecture - The Cathedral is a given, but the fantastic thing about Canterbury is that so much of it is preserved. A lot of the city wall still stands, and there are plaques aplenty around town, explaining the significance of certain buildings and churches, places where they and the old city gates used to stand. At the moment I'm living in a 400 year old former pub, which is attached to the city wall and used to be a site of one of the old city gates.
I also like a good night out pub crawling / getting drunk etc - the hundreds of Canterbury pubs will suit you well with that! The campus is very relaxed, you can get in at any time (provided you remembered your key).
Any other questions, don't hesitate to message me!
