About MARIGNOLI DI MONTECORONA FOUNDATION INC

The Marignoli di Montecorona Foundation Inc. is a U.S.-registered private foundation (EIN 46-0618691) that supports scholarly research, publications, exhibitions and cultural projects focused on Italian art. The foundation is affiliated with a larger Marignoli di Montecorona cultural program active in Italy and maintains a donor-facing presence through grantmaking and sponsorship of conferences and exhibitions.

The EIN and tax status were confirmed from public U.S. filings for a private foundation; the organization has filed Form 990-PF returns and reports grantmaking and program expenses in recent years. In the last three years the foundation reported multi-hundred-thousand-dollar revenue and made direct charitable disbursements to support research, exhibitions and scholarship programs.

Operational activity in recent years has included underwriting scholarly conferences and exhibitions, supporting art-historical publications and maintaining an art-research/library initiative in collaboration with cultural institutions in Italy and elsewhere. The foundation presents itself publicly through its website and participation in cultural committees and events, and it is an active grantor rather than a membership-based or internal family trust only.
