The Fountain, one of the many historical monuments of seventeenth-century Rome, currently stands in an elevated position, on a large staircase in the center of Piazza Trilussa. Its façade was originally located between two marble doors of one of the façades of the Mendicants’ Hospice, forming the backdrop to Via Giulia. It was then transferred to the Square, after demolition at the end of the nineteenth century, maintaining its façade unchanged which today constitutes the main front, towards Ponte Sisto, of Castle V of Paola water distribution. The critical state in which the fountain finds itself, which over the last decades has only been subject to partial maintenance interventions, has led the Superintendency of Cultural Heritage of the Municipality of Rome to include the restoration intervention among the priority ones. Urban Vision sponsored the financing of the works.
