The overarching mission of INTO is to promote the conservation and enhancement of the cultural and natural heritage of all nations for the benefit of the people of the world. INTO is an international network of National Trusts and similar non-governmental organisations, globally diverse but united in a shared commitment to work through cooperation, coordination and comradeship. INTO works to develop and promote best conservation practices, increase the capacity of individual organisations, establish Trusts where they do not presently exist, and advocate in the interests of heritage conservation.
