The boxes have been painted by artist Meire Gomes as part of an initiative to increase interest in art in the municipality, as well as improving the quality of the urban space.
The project first began in the municipality in 2016, with the graffiti painting of the electricity boxes scattered throughout the city of Silves, as part of the commemoration of the International Day of Educating Cities, which was later extended to the rest of the parishes in the municipality, and which the Municipality of Silves intends to continue to promote in the localities of the municipality.
