Olentzero is a mythological coalman who brings gifts on Christmas and lives 10km away from Gorliz, in the town of Mungia, in Izenaduba forest. Other characters of the basque mythology are found there too.
Olentzero produces coal during the year, and when Christmas arrives, he goes door to door delivering the gifts he brings in his sac. Although only to those that behaved well as leaves coal to those that didn´t. So beware. Olentzero sees everything!
