No. 49 Bankside, SE1

This small house next to the Globe Theatre on the Southbank appears fairly ordinary. However, it has two notable features. The first, is that it is the oldest house in the area, dating from 1710. The second (related to the first) is that it has had its history (from a time before it existed) researched and turned into a book - The House by the Thames (History), (Amazon). If that sort of history leaves you cold I recommend you don't touch it, but otherwise, it is strangely compulsive reading.
