The iconic Washington Monument has been reopened to the public for the first time in three years.

A plaque commemorating the 1916 Easter Rising was hung inside the monument while it was closed for renovations.

The US First Lady, Melania Trump, attended today's reopening ceremony.

Also present was the Acting White House Chief of Staff, Mick Mulvaney, who accompanied Irish officials to view the 1916 Rising plaque.

"This is about the contribution Irish-Americans have made to this structure and to this nation," he said. "It's nice to know this plaque will be here along with all these other fantastic monuments."

The plaque, which contains the wording of the 1916 Proclamation, was presented to the US National Park Service on behalf of the President and people of Ireland to mark the anniversary of the 1916 Rising.

The Minister of State, Kevin 'Boxer' Moran, and Fianna Fáil Senator Mark Daly, travelled to the US for the unveiling of the plaque.
