Tie a piece of cloth around the old oak tree
The strange new look for Basel's Berower Park
Two artists in Switzerland have been wrapping up trees for Christmas.
Christo and Jeanne-Claude are well known for such large-scale work.
Now the husband-and-wife team have turned their attention to the natural world, with over 160 trees at the Berower Park in Basel all getting a new look this winter.
Although less grandiose than earlier projects, Christo has clearly been enjoying directing the latest challenge.
"It was impossible to shape the forms in advance. That's the exciting thing about this project," he said.
"Each tree has its own personality."
The project involves 55,000 square metres (461,000 square feet) of woven polyester and 23 km (14 miles) of rope.
This material lets air pass through, and is used in Japan to protect trees in winter, but Claude said the material has more than practical use.
"The cloth is the principle element to display the vulnerability, fragility and temporary character of our project.
"Of course that uniqueness creates a different kind of looking art"
The display coincides with a "Magic of Trees" exhibition inside the museum, which pays tribute to the way artists such as Picasso, Chagall, Cezanne and Giacometti have represented trees through the centuries.
Museum curator Marcus Brunderlin believes the work of Christo and Jeanne-Claude will stand the test of time.
"We will remember in a few years the wrapping of the Reichstag because it's a part of German history," he said.
"It's like summer again in the winter," said one. "That's fascinating."
But Jeanne-Claude warned people not to look too deeply.
"Our works of art are like all good art," she said.
"It is good for absolutely nothing else than being a work of art. It is not the symbol, it is not the message, it's only a work of art."
The wrapping will be recycled as the trees themselves regenerate leaves for their more conventional summer appearance.
