Chetham's Hospital, just north of Manchester Cathedral, dates in part to 1422. Originally a residence for priests, it's now home to a music school and Chetham Library, one of the oldest public libraries in England.
In continuous use since 1653, the library has more than 100,000 books, more than half of them printed before 1850. Chetham's is also famous as the meeting place of Karl Marx and Friedrich Engels during Marx's visit to Manchester.
