Monti Cimini, located few kilometers south of Viterbo, represent the core of one of the principal hazelnut production areas of the world. In an area of 33,000 ha there are over 9,000 farms that produce hazelnuts “Tonda Gentile Romana” covering approximately 18,000 ha and giving an average year production of 40,000 tons (corresponding to more than 5% of the world production). The high productive specialization has contributed to the creation of a very dynamic sector, where several hazelnut farmer associations as well as firms specialized in assembling specific harvesting machines or in processing and marketing are present. Taking into account the international importance of the Monti Cimini hazelnut district, Viterbo has been chosen as the official seat for the next international congress on hazelnut which will be held from the 23rd to the 27th of June 2008.
