A passage to....?

I like the shadows that trees and objects cast on walls and on the streets and I like to shoot them a lot... maybe too much.

This one is pretty peculiar though, not because of the tree itself, but rather for the weird "neo classical" portal that goes no where...
It reminded me of some creepy movie where ancient doors where bricked up close in order to keep the "unknown" on the other side; of course this is not the case, but it's a much more common Shanghai building anomaly (forgive me the oxymoron)... no paranormal involved except China itself of course!
