In Daumesnil, 12th arrondissement, the largest market of Paris takes place. Noisy, multicultural and throbbing are the classic keywords that can come to mind when talking about this subject. I wondered what the market could be other than this concentration of colours and interactions. I found the answer in the physical work of the workers before the sales day, in the wake-up alarm when the city is still immersed in the darkness of the night and in the systematic and efficient work of the sweepers at end of the day. The calm before and after the storm.
