FAI
N.E.T. Ltd. decided to support the FAI – The Italian National Trust - by adhering to the corporate membership programCorporate Golden Donor. Together with FAI, we would like to realize a big protection project and an ambitious culturalchallenge: make Italy a more beautiful place to live, work and bring up our children. The natural and cultural Italianheritage, protected and promoted by FAI, represents the most important resource to invest on, in order to develop andpromote our beautiful country. Thanks to the help of its many supporters, both private citizens and Companies, FAI hasbeen protecting and managing 56 Italian cultural sites, over the past 40 years: many important historic and artisticsettlements had been saved from carelessness, restored, protected and opened to the public.
Every day, FAI is committed to protect and to make
accessible all artistic, natural and cultural jewels which
are located in the countryside, the cities and the coasts
of our beautiful country. Our aim is to educate and
sensitize the international community to the
knowledge, respect and care for art and nature, to
convey the demands of civil society by being actively
present on the territory.
We want a more protected beautiful Italy.
We work with FAI to build it.
