The Trevi Fountain, arguably the world’s most famous, has graced screens for decades, from Fellini’s “La Dolce Vita” to Netflix’s “Emily in Paris.” Each year, millions of visitors push through Rome’s narrow streets to gaze at the towering Titan god flanked by falls cascading into a turquoise pool. Yet, they never get to venture behind Oceanus’ back to see what’s behind the magical play of water in this baroque masterpiece. Wooden doors on an adjacent street lead to the maneuvering chambers, which control water coming from the Aqua Virgo — an ancient Roman aqueduct 16 kilometers away.
