Embassy of the United States, Dublin

The embassy was designed by American architect John M. Johansen, in consultation with Irish architect Michael Scott.[3] It was constructed between 1962 and 1964 on a triangular site at the intersection between Elgin Road and Pembroke Road. A Victorian house was previously on the site, and had been used by Bord Fáilte as their headquarters. It was constructed by G&T Crampton.[4] The building was officially opened on May 23, 1964 (1964-05-23) by Congressman Wayne L. Hays.[5]

The new building is circular in plan,[6] incorporating modern interpretations of early Celtic and later Irish buildings with contemporary, bold American design as well as symbolising the first American flag, and is considered a Dublin landmark.[7] There are five floors at the complex, two underground and three above ground, plus a smaller sixth storey on the rooftop.[8] The ambassador, Grant Stockdale, proclaimed the building "the showpiece of Europe". Among Dubliners, it acquired the name "Wall of Death" owing to its circular shape. Despite the modern design, it is deemed to sit well in its Victorian context as it of similar height to the surrounding buildings.[4]

On 23 May 2011, a 2005 model Cadillac Presidential State Car was involved in an incident when it got stuck on a ramp as it exited the U.S. Embassy during an official visit by President Barack Obama. It is understood that the wheelbase of the vehicle was too great for the ramp, and it had to be towed off the ramp as a large crowd looked on. President Obama left the embassy through an alternative exit. The U.S. Secret Service later stated that the car was a spare, and that President Obama and First Lady Michelle Obama were in another vehicle.[9]

Deerfield Residence, a large 18th-century house on over 60 acres (24 ha) in the Phoenix Park, has since 1927 been the United States Ambassador's Official Residence in Ireland. Before the 1960s, the embassy was located at the grounds, then known as the Chief Secretary's Lodge. The United States first opened a consulate in Ireland in 1859 at a building on Adelaide Road, Dublin 2, and also had a presence at Merrion Square, Dublin 2 from 1948.[10] Both current diplomatic premises are owned and operated by the United States Department of State on behalf of the United States federal government.

In late 2012, the United States Department of State announced the embassy will move to new location within a number of years. The chancery in Ballsbridge, which was 50 years old in 2014, has been deemed "no longer suitable", and an embassy spokesperson stated that the current building no longer meets the needs in terms of size of the expanding American diplomatic presence in Ireland (between 150 and 200 staff work at the embassy),[11] and does not conform to new construction and security requirements ("code") issued by Washington D.C.[12] A number of sites around Dublin City are being considered for the construction of a new embassy building, which will be on larger grounds, will be a larger building than the Ballsbridge Chancery, and may be located nearer to the Ambassador's Residence and Dublin Airport for security reasons and ease of access. However, completion of the move to a new embassy facility is likely to take up to 10 years and cost tens of millions of dollars.[13]
