Monaco Joins the America250 Commemoration Through Historic Partnership
April 28, 2026
The Principality of Monaco formally joined the United States’ 250th anniversary commemoration with the signing of a Memorandum of Understanding (MoU) with the America250 Commission on April 28 at the Residence of Monaco in Washington.
Hosted by H.E. Maguy Maccario Doyle, Ambassador of Monaco to the United States, alongside The Honorable Rosie Rios, Chair of the America250 Commission, the event marks a new chapter in the longstanding relationship between Monaco and the United States.
The agreement places Monaco among international partners contributing to America250, with a focus on cultural exchange, education, and forward-looking dialogue. In her remarks, Ambassador Maccario Doyle noted that the partnership “reflects not only a shared history, but a shared commitment to shaping the future together,” while Rosie Rios underscored the importance of international engagement in the commemoration.
The signing took place during a year of significant milestones, including the 250th anniversary of the United States, the 20th anniversary of Monaco’s diplomatic presence in Washington, and the 70th anniversary of the marriage of Grace Kelly and Prince Rainier III.
The evening brought together leaders from diplomacy, culture, and industry, including Charles Rivkin, Chairman and CEO of the Motion Picture Association and former U.S. Ambassador to France and Monaco; René Augustine, Vice President of Global Government Policy at Paramount; J.B. Kelly, President of the Prince Albert II of Monaco Foundation–USA; Ginna Levine of the Princess Grace Foundation–USA; and Bill Nelson, former NASA Administrator, U.S. Senator, and astronaut.
The event also served as an opportunity to reflect on the deep historical ties between Monaco and the United States. More than a century ago, Prince Albert I traveled extensively across America in pursuit of scientific discovery and exploration. During one of his journeys, he visited Wyoming, where he hunted with the legendary Buffalo Bill at what became known as “Camp Monaco.” Prince Albert I later visited Washington
in 1921 and met with President Warren G. Harding, making it particularly meaningful that the agreement was signed at the Residence of Monaco, once Harding’s home before he entered the White House.
The connection between Monaco and America was further strengthened through Prince Albert I’s marriage to Alice Heine, who was born in New Orleans, and later through the iconic union of Grace Kelly and Prince Rainier III, a transatlantic story that
continues to resonate nearly seventy years later.
As Ambassador Maccario Doyle emphasized, the MoU is not simply about commemorating milestones, but about honoring a shared history, strengthening the ties between the two nations, and carrying that friendship forward for future
generations.
