If you love a little bit of history and you also love to read, then Chetham's Library might be a worthwhile trip. Established in 1653, it's the UK's oldest free public library (although to visit you must make an appointment).
Housed in the most incredible 15th-century Baronial Hall, the stunning dark-wood aisles are packed to the rafters with all kinds of publications from 'large folio books to manuscript diaries, letters and deeds, to prints, paintings and glass lantern-slides'.
There's also an incredible selection of archives, newspaper cuttings and old photographs. In fact, all together, there are over 100,000 publications here, the majority of which were printed before 1850. If anybody has ever read 'Shadow in the Wind', you might have some idea of how special a place this is and what a wonderful insight it can give you into our heritage (note that to see specific material you'll have to enquire).
A nice little bit of trivia: this is a library where Marx and Engels would meet, you can see exactly where they sat and what book Marx was reading at the time. Ok, I'm a geek. What can I say?
