What is IMRI?

The International Marian Research Institute is one of the largest international centers of study, research and teaching on Mary, the Mother of Jesus Christ.

Our goal is to gather and present information about the Virgin Mary and to lead people to a loving knowledge of her. In learning more about Mary, we develop a more complete knowledge of Christ, His Church and Christian life. This global, scholarly and pastoral mission is fulfilled through the operation of the educational program, library, gallery, museum, as well as through research, publication, speaking engagements and various other forms of outreach, both actual and virtual.
