The French capital's iconic waterway has been largely closed to swimmers since 1923 due to pollution and risks from river navigation.

First, France cleaned the polluted river so that Olympians could swim there. Now, a year later, it is opening three sites for locals to plunge in.

The famed Seine river in Paris opened to the public for swimming on Saturday for the first time in over a 100 years, a key victory for outgoing mayor Anne Hidalgo.
