Some areas of Paris are under water after the River Seine burst its banks following days of heavy rain.
Several roads along the river banks were closed from the east of the French capital to the Eiffel Tower in the west.
Water levels rose at least 3.3m above normal levels after heavy rains lashed the country over the past few days.
The water is set to rise even more in the coming days, weather forecasters said.
Friday could see the Seine reaching 6.10m, its highest levels since June 2016 when several iconic monuments had to be closed, including the Louvre Museum where curators scrambled to save precious paintings.
Seven Paris RER stations, which run under the Seine, will be closed for several days from Wednesday, railway company SNCF said.
Boat cruises through the city of love were also cancelled.
Italian tourist Costanza Della Cananea said: “We are disappointed because we thought we were going on a cruise on the Seine.
“It was the first time we were going to do it.”
Marina Franchi, visiting from Marseille in the south, was meant to be going on a dinner cruise.
“It is a part of our heritage. It would have been nice to visit Paris by night on the Seine,” she said.
Authorities warned several rivers in eastern France could also burst their banks due to heavy rain over the past few weeks.
