About Governors Island National Monument
From 1794 to 1966, the U.S. Army presence on Governors Island played a vital role in the social, political, and economic life of New York City. The island then served as the headquarters of the U.S. Coast Guard from 1966 to 1996, continuing its legacy of national service. Today, Governors Island has transformed into a destination for art, culture, and public programs.
