A not-to-be-missed street art event in Paris this autumn! The City of Paris has announced the opening to the general public of Le Mausolée, a disused former supermarket occupied by the duo Lek & Sowat and some twenty street artists between 2010 and 2011. Fifteen years after its creation, this astonishing and unusual site, located in the 19th arrondissement of Paris, is preparing to welcome the public from October 1, 2025 for a series of free guided tours. We were lucky enough to visit this unique site, a veritable temple to graffiti and urban exploration. We tell you all about it by torchlight.
