The world’s most visited museum, the Louvre in Paris, is to close on Friday amid worsening flooding caused by days of torrential rain.
The move will allow staff to move works at risk of damage to higher parts of the gallery, a statement said.
The Seine, which runs through Paris past the Louvre, has risen five metres above normal levels.
Heavy rains across Europe have left at least 10 people dead, most of them in Germany.
More downpours are forecast right through the weekend across a band of central Europe from France to Ukraine, with as much as 50mm (2in) of rain falling in some parts in just a few hours.
Transport, tourism hit
Emergency barriers are being put up along the Seine, which burst its banks in places. Its levels are forecast to peak overnight.
Announcing the closure, the Louvre said: “The aim is to move works situated in areas vulnerable to flooding to safety by moving them to higher floors.”
Another much-visited attraction, the Musee d’Orsay, shut its doors on Thursday.
Rail operator SNCF announced the closure of the RER C line, which runs alongside the Seine in central Paris from 16:00 local time (14: 00 GMT).
About 25,000 people are without power in Paris and central France.
In Nemours, 3,000 people have been evacuated from the town centre.
The town’s Loing river, a tributary of the Seine, now has levels not seen since the devastating floods of 1910.”The centre of town is totally under water. All the businesses have been destroyed,” said mayor Valerie Lacroute.
Gwen Bonpaix, 18, who lives in Montcourt Fromonville, 5km (3.1 miles) from Nemours, told the BBC part of the village was flooded.
“The electricity doesn’t work, and we can’t use our toilet because the sewers are also getting flooded,” she said.
“My home hasn’t been flooded yet, but the water has already reached the garden, and it’s still raining. We’re going to leave before we get stuck here.”
Six weeks’ worth of rain has fallen in three days in the Loiret department. It submerged roads, forcing drivers to abandon their cars.
