or the Wilson Palace

From wikipedia

In 1924, the building was named after U.S. President Woodrow Wilson, who was instrumental to the foundation of the League of Nations.

It was also the headquarters of the League of Nations from 1 November 1920 until that body moved its premises to the Palais des Nations on 17 February 1936.

Today, 19th-century headquarters for the Office of the United Nations High Commissioner for Human Rights.
