Cincinnati's "Old Main" / by Rob Fleming

Cincinnati, Ohio’s current downtown public library branch is grand in its own right as one of the busiest branches in the country. But its predecessor, demolished in the spring of 1955, was nothing short of stunning. Built in 1874, the ‘Old Main’ library was originally intended to be an opera house, with a towering atrium that instead became home to five tiers of stacked bookshelves.
