Dublin's iconic department store, Arnotts, has unveiled its 2017 Christmas windows.

Each year, the story in the Christmas windows begins in the North Pole and this year is no different - with more animation and interaction than ever.

This year, Arnotts says the Christmas windows are all about 'Santa Mail' and tell the story of the journey taken by letters sent to Santa.

The concept around the festive windows have been a year in the making, with the idea first being created in December last year.

Damien Byrne, head of creative at Arnotts, said: "This year we have more animation and interaction in the windows than ever and we are hoping that all of the families who visit Arnotts this season will make the experience of the Christmas windows part of their story of Christmas."

The windows will be filled with all the characters children love to associate with Christmas: snowmen, polar bears, penguins, Santa’s elves and, of course, Santa’s reindeer.

Last Christmas Arnotts introduced its very own Christmas reindeer, Crackers, who will be making a re-appearance this festive season.

Every year, the store donates all the toys showcased in the Christmas windows to a children’s charity.

The department store will also introduce a special dedicated ‘Christmas Wonderland’ on the second level beside Santa’s Grotto.

And the man himself, Santa Claus, will be making his way to Arnotts by horse-drawn carriage from Sunday November 19th.
