"You can't sleep here!"

The appalling sight of metal spikes to stop homeless people sleeping outside the doorway of a vacant building on Rambla de Catalunya in Barcelona. 

I took this photo this week. Not in the early 20th century. 

Londoners and New Yorkers will also recognise this anti-human architecture.

I first wrote about this (and a related) theme in this article tilted "Poor Doors" in 2014.
