It was actually being built the last time I walked along that part of the Thames (makes me feel old).Well I could tell you this is Shakespeare's Globe theatre, built in 1599, rebuilt after a fire in 1614...
But it's actually a reconstruction from 1997.
Some would say, 'fake'.
But thousands of international tourists don't read the small print every year and go home thinking they've seen a 400 year old building.
