<P> In January 2013, it was announced that the Italian fashion company Fendi would sponsor a 20 - month, 2.2 - million - euro restoration of the fountain; it was to be the most thorough restoration in the fountain's history . </P> <P> Restoration work began in June 2014 and was completed in November 2015 . The fountain was reopened with an official ceremony on the evening of November 3, 2015 . The restoration included the installation of more than 100 LED lights to improve the nighttime illumination of the fountain . </P> <P> The backdrop for the fountain is the Palazzo Poli, given a new façade with a giant order of Corinthian pilasters that link the two main stories . Taming of the waters is the theme of the gigantic scheme that tumbles forward, mixing water and rockwork, and filling the small square . Tritons guide Oceanus' shell chariot, taming hippocamps . </P> <P> In the centre a robustly - modelled triumphal arch is superimposed on the palazzo façade . The centre niche or exedra framing Oceanus has free - standing columns for maximal light and shade . In the niches flanking Oceanus, Abundance spills water from her urn and Salubrity holds a cup from which a snake drinks . Above, bas reliefs illustrate the Roman origin of the aqueducts . </P>
