This work objective will contextualize the mnemic codes circulated in the Famalicão Urban Garden Vegetable, located in northern Portugal. This place has 259 earth plots and 179 citizen-gardeners and we focus on the largest part of this group: a senior community. This semiosphere presents a series of common cultural texts that aid in delimiting its border. In turn, we also can think of it as a heterotopic reference (Foucault), because it welcomes people at a stage of life in crisis, as happens with the elderly/retired we propose to talk about here. As affirmed Lotman, memories are part of the cultural texts of a semiosphere and in this urban vegetable garden, those codes are latent. This elder group are building similar memories due to the common life stage they are experiencing in this semiosphere, but also added other common cultural codes linked to their previous memories: a childhood in the countryside; living through the period of Salazar's dictatorship; leaving the countryside in their youth to move to the city - or to pursue a life as emigrants. Those memories are expressed in each earth plot, where we observe their narratives, the objects applied or the agricultural techniques used there. This study began in 2023 and is based on field research. The flanerie strategy has been used, as well as the ethnography based on the Anthropology of Food, and it is ending, with the application of 24 semi-structured interviews.
