The Associazione Vera Pizza Napoletana is an international organization officially established on June 1984 by a group of Neapolitan people representing some of the oldest families of pizza makers and the most famous Neapolitan pizzerias, seeking to cultivate the culinary art of making Neapolitan pizza. Later on, the association was officially established by the Italian government as a denomination of control (DOC), a designation that made AVPN a legal entity able to give special designation to pizzerias who meet strict requirements that respect the tradition of the art of Neapolitan pizza making.
