     Holidaymakers who are bored with baking beaches and overheated hotel rooms head for a big igloo.

Swedish businessman Nile Bergqvist is delighted with his new hotel,the world's first igloo hotel.Built in

a small town in Lapland,it has been attracting lots of visitors,but soon the fun will be over.

     In two weeks' time Bergqvist's ice creation (作品) will be nothing more than a pool of water." We

don't see it as a big problem," he says. "We just look forward to replacing it."

     Bergqvist built his first igloo in 1991 for an art exhibition.It was so successful that he designed the

present one,which measures roughly 200 square meters.Six workmen spent more than eight weeks piling

1,000 tons of snow onto a wooden base:when the snow froze,the base was removed. "The only wooden

thing we have left in the igloo is the front door," he says.

     After their stay, all visitors receive a survival certificate recording their success.With no windows,

nowhere to hang clothes and temperatures below 0℃, it may seem more like a survival test than a relaxing

(轻松的) hotel break. "It's great fun,"Bergqvist explains,"as well as a good start in survival training."

     The popularity of the igloo is beyond doubt:it is now attracting tourists from all over the world.At least

800 people have stayed at the igloo this season even though there are only 10 rooms."You can get a lot of

people in," explains Bergqvist. "The beds are three meters wide by two meters long,and can fit at least four

at one time."
