. The former embassy chancery on Henrik Ibsens gate in downtown Oslo was designed by Finnish–American architect
Eero Saarinen, who also designed the
American embassy in London and the
Gateway Arch in Saint Louis, Missouri. It was completed in 1959, four years after Saarinen was first selected for the project. The base of the building forms a horizontal triangle with a dark exterior, which lead to poor circulation and offices with abnormal shapes but also gave it a modern appeal and was well-suited for receptions. Physical security measures, including a fence surrounding the chancery, were added after the
September 11, 2001 attacks in the U.S. As of June 2016, some of the windows had the colors corresponding to those of the
Rainbow Flag to give recognition to
Pride Month.
New chancery For years, officials searched for a new embassy location. The suggestion to build in a former forest became controversial, as many feared it would permanently shut the public out of the area. In December 2005, the Oslo City Council decided with the least possible majority that the embassy should be offered a new embassy area in Huseby Forest, not far from Makrellbekken subway station. On 14 May 2012, the
groundbreaking ceremony for an embassy at the new location was conducted in Oslo. The project has a particular focus on environmental features and is constructed by Walsh Group of Chicago and the architects/engineers are
EYP Architecture & Engineering. The new embassy meets stricter requirements for security for US embassy buildings. It opened on 15 May 2017.
2026 explosion On the night of 8 March 2026, an explosive device detonated at the consular entrance of the embassy. The explosion caused material damage to the building, but no one was injured.
The Norwegian police stated that the blast was likely caused by an
improvised explosive device and launched an investigation into the incident. This device was placed at the building's entrance. On 11 March 2026, three men in their twenties were arrested and charged with terror bombing. == Embassy sections ==
