An illuminated 18-metre long cardboard bridge suspended by three large white helium balloons is floating above the Tiber river, delighting passers-by who stopped to take pictures of the unique, picturesque installation.
The bridge connects the Renaissance building that houses the French embassy to the gardens of Villa Farnesina in Trastevere.
It was inaugurated on Tuesday evening (July 13), the eve of France's Bastille Day.
It will remain in place for a few days before being dismantled on July 18. The cardboard will be recycled.
