In 1989 the headquarters of Interpol were relocated to which French city?

In the first part of the 20th century, several efforts were taken to formalize international police cooperation, but they initially failed. Among these efforts were the First International Criminal Police Congress in Monaco in 1914, and the International Police Conference in New York in 1922. The Monaco Congress failed because it was organized by legal experts and political officials, not by police professionals, while the New York Conference failed to attract international attention.

In 1923, a new initiative was taken at the International Criminal Police Congress in Vienna, where the International Criminal Police Commission (ICPC) was successfully founded as the direct forerunner of INTERPOL. Founding members included police officials from Austria, Germany, Belgium, Poland, China, Egypt, France, Greece, Hungary, Italy, the Netherlands, Romania, Sweden, Switzerland, and Yugoslavia. The United Kingdom joined in 1928. The United States did not join Interpol until 1938, although a US police officer unofficially attended the 1923 congress.

After the end of World War II in 1945, the organization new headquarters were established in Saint-Cloud, a suburb of Paris. They remained there until 1989, when they were moved to their present location in Lyon.
