In 2014, the spot was entirely covered with illegal advertising or political posters, pasted up since the 1980s.
In the different layers, posters for the Feast of Sant'Efisio, the circus, and electoral pamphlets were found.
The Urban Center team spent several days removing posters to free the walls, and in 2014, with the start of the project, those walls were painted by Marcello Marinelli, Billy, Bof, Carol Rollo, and Neeva.
In 2016, Marinelli and Gregorini created two more works, and in 2023, Crisa also contributed.
Between 2020 and 2021, a political group began re-pasting posters with political messages over the works, gradually encouraging other political groups to do the same.
On April 25, 2023, the organizing association recognized this dynamic as a natural return of the spot to its previous use and called on other groups and associations to formally designate the area as a spot for poster posting.
Today, various types of posters are affixed in the space, making it one of the areas of the Gallery dedicated to the laboratory activities of the Urban Center.
