The project was created to permanently house the personal collection of the renowned goldsmith Fernando Marmolejo, who lives in Santiponce, and to disseminate the rich heritage of the population linked to the archaeological site of Italica and the monastery of San Isidoro del Campo, in non-permanent exhibitions. The building is located on the outskirts of Santiponce, facing east on the site once occupied by the municipal slaughterhouse. The privileged location of the museum in the town, very close to the Roman Theatre, and close to Italica, makes it possible to include it in a tour of the Roman city. On the other hand, the proximity of the fairgrounds places the building in the context of Santiponce's recreational spaces and visually connects it to the fertile plain of the Guadalquivir. The building is isolated from the outside reality, to become absorbed and create its own place. The presence of the party wall of the adjacent building, along the greater dimension of the building, allows a unitary reading of the space of the Museum that is proposed, as fragmentary. The zenithal light in specific places on the roof accentuates a sensitive experience in which light carves the spaces, transforming them throughout the day. On the ground floor, the structure compartmentalizes the space, which is fragmented and communicated at the same time, through the multiplicity of points of view and routes. The changes of scale, the different levels of the floor, the crossed visions, allow to create the illusion of a space that expands up to where the view reaches. The superior zone of the building is a sequential route in which the spaces that already were guessed in ground floor are followed, and that reach their definitive form in the elevations and the covers of the building crystallizing the forms that are intuited in the interior.
