Christmas Eve is approaching fast and here in the Arctic Circle one jolly old man and his helpers are busy preparing for their biggest night of the year.

This is Santa Claus village.

Inside the main post office, around half a million letters are being sorted according to country and read in their original language.

Throughout the year Santa Claus resides in this village located in Rovaniemi in Finland, where over 300,000 people visited him last year.

But in about a week he will visit children everywhere when he makes his famous round-the-world journey.
