Fodor's Expert Review Bank of England

Since its establishment in 1694 as England's central bank, the role of the "Old Lady of Threadneedle Street" (a political cartoon caption that stuck) has grown to include managing foreign exchanges, issuing currency, storing the nation's gold reserves, and regulating the United Kingdom's banking system. Since 1997, it has had operational responsibility for Britain's monetary policy, most visibly setting interest rates (similar to the Federal Reserve in the United States).

The 3-acre site is enclosed in a massive, neoclassical curtain wall designed by Sir John Soane. This 1828 windowless outer wall is all that survives of Soane's original bank building, which was demolished in 1925. You can discover more about the bank's history in the surprisingly varied Bank of England Museum (the entrance is around the corner on Bartholomew Lane). In addition to the bank's original Royal Charter, there's a lively program of special exhibitions, plus interactive displays (you can even try your hand at controlling inflation). The most popular exhibit remains the solid-gold bar in the central trading hall that you can actually hold—but before you get any ideas, there's security everywhere.
