I heard that Santa Claus used to live at the North Pole. In 1925 he moved to Korvatunturi, which was on the border between Finland and Russia, about 300km north of Rovaniemi, because of the lack of food for his reindeer. And he still lives there...it is said.
The reason why he is at the Santa Claus village every day is because the roads between Korvatunturi and Rovaniemi are not maintained. It is too hard to go to see Santa Claus for people so he commutes to Rovaniemi to meet children and adults who still believe in him! As a result, the Santa Claus village in Rovaniemi has become one of the greatest resources for tourism, along with the northern lights and winter activities. About more than 5 hundred thousand tourists visit there from all around the world every years!! What a huge market!
