This is the former public records office, dating from 1856, and now the library of the esteemed educational institution King's College London. It was open to the public during Open House Weekend, when I found out that King's is one of the top 10 universities in the World. The library is certainly impressive, holding over 750,000 publications, including various special collections which can be accessed by appointment. The building is also quite amazing, occupying an historic site. The round reading room and the Weston Room were the most impressive, the latter being where they have special displays (one currently on American poetry).
