The Carnival of Naousa is an old Greek traditional event and attracts many visitors.  Men wearing traditional uniforms, dance across the streets of this beautiful Macedonian small town.  The Carnival of Naousa is traditional and called Genitsaroi and Boules, a custom that derives from the ottoman occupation era.

Sunday of the Carnival. The gathering of the group: The young man dressed up from the previous evening in later years, and from early morning nowadays, is ready. The drum and the clarinet (zournas) are heard from far away calling for the group to gather. The musical instruments, playing a melody of the free rhythmic type, called Zalistos, will pass by all the houses of the young men who participate in the group and they will gather them one by one.
