Inspired by the plants of the Sahara col­lected by Abdessamad El Montassir, we will search for plants, those that resist the inva­sion of con­crete and the city in our imme­diate envi­ron­ment. After a stroll through the streets near the art centre, and in the manner of the botanist Anna Atkins, we will create the very first herbarium of the neigh­bour­hood using her pho­to­graphic print tech­nique: the cyan­otype.
