If you're into old towns and landscapes, you could do worse than a walk along the riverside (near the bear enclosure), there's a nice bridge there, and when i was there there were some wonderful views across the river.
If you like more modern/geometric places, you might like the museum for communication, which has some interesting exhibits, but some wonderful opportunities for light and shade.
I'll attach a a couple of pictures for you (even if they are digital and awful, they're not really the best advert for it, but I only had a rather old digital camera with me, should have probably taken film).
