The Acqua Paola Fountain in Piazza Trilussa dates back to 1613 and is the work of the Flemish Jan Van Santen (known in Italy as Giovanni Vasanzio) and Giovanni Fontana. Commissioned by Pope Paul V, it is located in Piazza Trilussa, one of the squares of Roman nightlife. It immediately presents itself to the visitor in its form, conceived as a monumental arch.
The high attic on which the coat of arms with eagle and dragon of the Borghese family is clearly visible is striking. Another detail that strikes the attention is the celebratory inscription which explains the merits of Pope Paul V in relation to having brought new water to the left bank of the Tiber as well. Structurally it consists of a monumental arch with a central niche and flanking columns. A scenic structure of great impact, also because it is placed high up, at the top of the steps, and therefore dominating the square.
