The OVN Foundation aims to stimulate research into the history of freemasonry, for which the availability of historical sources is essential. The OVN Foundation therefore also contributes to the preservation of masonic cultural heritage, including historical archives, libraries, objects and buildings, and to efforts to make this heritage more easily accessible for research.
The OVN Foundation can offer its expertise for projects concering research, inventorying or conservation of masonic objects and buildings, and offers information and advice to students and academics, heritage professionals and the general public. The foundation also initiates heritage projects.

In 2010 the OVN Foundation launced a campaign to save the Cultural Masonic Centre in The Hague. The campaign was aimed at the heritage sector, local gouvernement agencies and all the lodges of the Order of Freemasons under the Grand East of the Netherlands. As the Order is considering to move the Centre to a location elsewhere in the Netherlands, a strong plea was made to allow the Centre to remain in The Hague, as the collections have been inextricable linked to the city for 300 years on both a historical and a physical level, and are part of the excellent (inter)national academic infrastructure of The Hague.
