The ruins of a landmark industrial building in Rome have become home to a thought-provoking art project that casts an unflattering light on the capital's patchy record on urban regeneration.

Sections of the abandoned shell of the Mira Lanza, once a factory where soap was first produced in Italy, are now home to a collection of works created by Seth, a French street artist who camped, illegally, on the rubbish-strewn site for two months last year.

Now looked after by a group of ethnic Roma migrants, who have set up camp inside the ruins, the paintings and installations created from the on-site debris are already starting to decay.
