Today’s U.S. Coast Guard presence in the Eastern Caribbean is the result of more than 100 years of growing service based in Puerto Rico and the U.S. Virgin Islands. The Sector San Juan Command is located at Base San Juan in the heart of the old city and ‘Quarters One’ is the centerpiece of the installation. Constructed in 1908, this building was originally home to the El Morro lighthouse keeper while the grounds of La Puntilla were used primarily to store aids to navigation. This base and the wide area of responsibility became the 10th Coast Guard District during World War II and was then absorbed into the Seventh Coast Guard District and renamed “The Greater Antilles Section” (GANTSEC) in 1945. GANTSEC and Marine Safety Officer San Juan were combined and restructured into Sector San Juan in September of 2004.
