The Vasari Corridor

The Vasari Corridor: The World's Least Secret Secret Passageway

What do you do if you're the 16th-Century Duke of Florence and you need a way of getting between your two palaces without being seen by anyone? You build a 1km passageway 3 floors up in the air, of course... - YouTube blurb

I just came across Tim, The Tim(e) Traveler, and he's pretty entertaining. His specialty seems to be going to strange, obscure places and giving us a bit of history.

The Duke was a Medici and we already know they were a big deal in Florence. Also enemies of the Borgia.

Tim's route starts at the Palazzo Vecchio on the left and follows the corridor along to the Palazzo Pitti on the right.

You can sort of see the corridor on Google Maps, but all the roofs on all the buildings in Florence are red tile, so it can be a little difficult to pick out.
