Bonn American High School (BAHS) was an American international school located in Bonn, Germany.
Among the thirty-four American high schools opened in Germany by the United States Government (USG) during the Post-War period, Bonn American High School (BAHS) was unique in that it was the only school in the world built and owned by the U.S. Department of State. Developed out of an elementary school that originally opened in 1952, it was intended to support the families of personnel at the U.S. Embassy – which grew to become the largest U.S. Embassy in the world with over 900 Americans and 600 local staff – in Bonn, West Germany, then the linchpin of the West's engagement during the Cold War. When BAHS opened in 1971, it was only the thirteenth USG high school in Germany, and although not associated with a U.S. Department of Defense military installation, it was staffed and run as part of the Department of Defense Dependents Schools system in an arrangement between the Department of State and the Department of Defense. BAHS closed in 1997 following the transition of the Embassy to Berlin, and was part of the Post-War American Plittersdorf settlement ,[1][2] now a protected historical area.
