I am staying in the City of London proper for the first time since I started frequenting the British capital in 1994. Most of the places Americans think of as "London"--Piccadilly Circus, the Houses of Parliament, Buckingham Palace--are, in fact, located in the City of Westminster. "Greater London" refers to the entire metropolis. But "the City" is the medieval core of the place, defined by just over a square mile on the north side of the Thames. It's pretty much the financial district for modern London.
The most visible landmark in the City is St. Paul's Cathedral, and from my hotel window I can see the front towers and the Dome of the imposing edifice less than a block away. I am also a 10-12 minute walk across the Thames--via theMillennium Bridge--from Shakespeare's Globe, the theater where I will be spending about 9 hours of my stay here this weekend.
