On August 12, 2010, French graffiti artists Lek and Sowat found an abandoned supermarket of 430,000sq. ft in the north of Paris. For a year, in the greatest of secrets they invited forty French graffiti artists to collaborate and create an illegal graffiti Mausoleum.
As the monument is not accessible for safety reasons, Lek and Sowat recreated a few murals and installations in an abandoned apartment to share their experience with the public .
