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.

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.

Bathing sites will be located near the French capital’s Notre-Dame cathedral, the Eiffel Tower and in eastern Paris.
