Rome's residents lashed out at the three girls for splashing in the city's Fontana dell'Acqua Paola, which dates back to 1612, according to the news website The Local.
The incident, which took place on July 8, was photographed by one of the eyewitnesses, who then posted the snaps on his Twitter page.
"It's very hot, but the fountain of Gianicolo [the common name for the Fontana dell'Acqua Paola] can't become a swimming pool for tourists. Rome deserves more respect," a tweet read.
Fa molto caldo ma il fontanone del Gianicolo non può diventare una piscina x turisti Roma merita più rispetto! pic.twitter.com/jbPIoHWghd— Trastevere (@TrastevereRM) 8 июля 2016 г.
Even though there was no immediate word on the women's nationality and country of origin, locals were quickly called upon to do "something similar in England or Germany."
