Quite possibly the city's most exclusive library, you'll find one of the most valuable book collections in the world, in this architecturally stunning building. Established in 1907 by the Boston Anthology Society, this is one of the oldest libraries. Exhibitions, concerts, seminars are regularly organized at the Boston Athenaeum. Though it is open only to members, on Tuesday and Thursday afternoons at 3p reserved tours for non-members are available for part of the library. The collections located here gave rise to the Boston Museum of Fine Art.
