The Marini Clarelli Santi Foundation is a private foundation set up in 2008 as a result of the testamentary provisions by Barbara Marini Clarelli, the widow Santi. The statutory purposes of this foundation are to allow the public to use the painting collection and the furnishings preserved in the Palazzo Marini Clarelli, that formerly belonged to the Oddi family, as well as to allow the civil and art history scholars to consult the library and family records.

In order to achieve the institutional goals, the Foundation may undertake and carry out any activities to promote education and art, as well as to protect, promote and enhance all things of artistic and historical interest.
