Igloos are usually constructed of tightly packed blocks of snow.
But the north-east’s very own version of the traditional Inuit shelter is made up of another readily available material.
Hundreds of milk bottle cartons have been glued together to form the structure at the Arbuthnot Museum in Peterhead.
For the last six weeks pupils from four of the town’s schools have been adding more of the white containers to the igloo for weeks.
It was set up as part of the Wondrous Whales exhibition at the museum.
The final pieces were put in place yesterday with children from Boddam Primary adding the last seven recycled bottles.
Jo Edwards, customer services officer at the museum, said it had been a joy to watch the structure grow.
She said: “It has been terrific.
“There have been schools in three times a week and the children even come back to see it.
“We are now trying to work out how to get it out of the building and find a new home for it.”
Hundreds of the plastic bottles have been collected by Buchan Day Opportunities, a centre that supports people with learning disabilities based at Willowbank near Peterhead.
Support assistant Stuart Noble, who has been helping to make the shelter in one of the museum galleries, said they now have enough cartons to create another igloo.
He has also been armed with a glue gun to make sure each of the plastic containers are stuck together.
Mr Noble said: “The igloo has been great and we’ve enjoyed watching it build up.
“It’s been good to have the schools involved.”
The igloo is large enough for an adult and a child to crawl inside and forms part of an exhibition inspired by whaling and Inuit life.
Wondrous Whales and Windy Sails also features painting, collages and a 19ft model of a whale.
It part of a council scheme to allow community groups to display their work at Arbuthnot Museum.
The exhibit is open until Saturday, March, 16.
