I adore this library! It's historic and charming and quintessentially British. It reminds me of Harry Potter; in fact, the fireplace was used (or was in inspiration) for the one in the novels/movies. It's the oldest free public reference library in the United Kingdom. Plus Chetham's was the meeting place of Karl Marx and Friedrich Engels. It's free to visit, but you'll have to join a guided tour. Look up tour times in advance. It's located within a school, so you'll need to be escorted.
Founded in 1653, Chetham's is the oldest surviving public library in Britain. The building dates from 1421, when it served as a priests' college. The library houses a vast collection of books, many of them centuries old, and an ornate reading room. It was in this room that Karl Marx and Friedrich Engels sat reading together during the summer of 1845; it is possible to sit in the alcove where they sat, and the books they read are still housed in the library.
The Cheatham Library is next to the Manchester Cathedral. It is at the Cheatham Library that Karl Marx and Fredreich Engle worked on the Communist Manifesto. And we know all to clearly how that pipe dream (nee nightmare) turned out for the workers in the former Soviet Union.
