Thanks for posting these. I went to Trent so I know the city well. Particularly nice is the number of churches downtown including a row of them on Reid St, just a block west of the downtown. The city also has some amazing brick homes (basically the whole town is made of brick) some of which date back to the 1800s.
I'll see if I have any pictures of the Trent campus around, because it really is one of the nicest campuses I've seen and probably one of the best examples of cement based architecture. For those interested here's a cool site that outlines the campus and shows some pics of the building process.
