Simon Harris TD, Tánaiste and Minister for Foreign Affairs and Trade, presided over the ribbon-cutting on September 25th at the Embassy’s new home at 1700 Pennsylvania Avenue NW, just steps from the White House designed by Irish architect James Hoban. The official opening was part of a broader programme of engagements by the Tánaiste in the U.S. capital.

In a letter, President Donald Trump welcomed the Embassy to the neighbourhood and acknowledged the historic relationship between the two countries, writing,

As you celebrate the grand opening of Ireland’s new Embassy location, I look forward to continuing to work closely with your country to strengthen our time-honored relationship…
President Donald J. Trump

Addressing the over 150 guests, including U.S. Secretary for Housing and Urban Development Scott Turner, Friends of Ireland Caucus Co-Chair Representative Richard Neal, and State Department Counsellor Michael Needham, the Tánaiste reflected on the value of the new location:

This will be an excellent base from which to grow our vital political, economic and cultural ties with the U.S. over the years ahead.
Tánaiste Simon Harris

The new chancery represents the culmination of a nearly four-year redevelopment plan. Its contemporary Irish design showcases Irish creativity and innovation, while paying homage to generations of strong transatlantic ties.

There is no greater sign of the importance of the Ireland-U.S. relationship than the opening of Ireland’s new embassy premises, next to the White House, in the heart of Washington, D.C. Since our first diplomatic representative was appointed to the United States in 1924, generations of Irish ministers, ambassadors, and officials have worked closely with U.S. administrations to build an enduring partnership. It is from this new office space that we will continue to deepen those ties.
Ambassador Geraldine Byrne Nason
