Pisa the action.

The builders of this leaning curved structure must have been on holiday in Italy before starting work.
 I was taking a few pictures when this complete stranger walked past me and adopted s propping up pose.  
It's on a long narrow way called Rope Walk although, as far as I can find out, it didn't have anything to do with the 19th. century process of making the long thick ships' ropes in the building opposite (please see extra.)

Many thanks to BobsBlips for hosting.
