5. Szabo Ervin Library in Budapest, Hungary
Budapest's Metropolitan Szabo Ervin Library was named after a 19th century aristocrat, which makes sense, given that its neo-baroque architecture was once located within the walls of said aristocrat's mansion.

Now, the Central Library's soaring spiral staircases rise up like something straight out of a storybook from within a larger, more modern library. You may be hard put to find it, tucked away as Ervin's library is, but it's well worth the search.

Found here.
