Leaders of the world’s biggest economies took time off on Sunday to visit Rome’s famous Trevi Fountain that dates back to the 1700s.

As the water gurgled behind them, the Group of 20 leaders each tossed a coin into the enormous Baroque-style fountain that has been the backdrop of many a film, most famously Fellini’s “La Dolce Vita,” according to an AP report.

Legend has it that if you throw a coin into the fountain, you’ll return to Rome.

The fountain, which draws its source from Rome’s ancient aqueducts, went through various phases of design before its current version was inaugurated in the mid-1700s. It depicts Neptune, the god of the sea, taming the waters. Built into a wall of the Palazzo Poli behind it, the fountain draws its name from its location at the confluence of three streets, or “tre vie,” in Rome’s historic centre.

The coins are regularly scooped out of the travertine basin of the fountain and given to charity.

The fountain is one of the most visited monuments of Italy and is loved by tourists. The historical fountain has drawn many filmmakers to it who have popularised the Baroque art-styled monument as the epitome of a place of romance.
