Image of 'Alligator Alcatraz' is AI-generated

"Alligator Alcatraz, Trump's new illegal immigration prison deep in the Everglades," reads a post sharing the image on July 2, 2025 to an Australia-based Facebook group with more than 114,000 followers.

The same image was shared by other Facebook users around the world, including in the United States, Canada and Greece. 

It did not just stay on social media -- several Greek websites also published the image alongside articles about Trump's visit.

The image circulated as Trump toured a new migrant detention centre in Florida in early July (archived here and here).

The new facility, dubbed "Alligator Alcatraz", is built at the disused Dade-Collier Training and Transition Airport deep in the Everglades, surrounded by swamps that are home to creatures including alligators and poisonous snakes.

Its name is a reference to Alcatraz Island, the former prison in San Francisco. 

Critics say the new facility is a symbol of the Trump administration's determination to look tough as it pursues its policy of mass deportations of undocumented migrants.

Some users in Australia appear to believe the image is genuine.

"I wish the Australian government would put their foot down on immigration. Love this idea," a user wrote.

Another commented, "That is A Huge Active Moat! surrounding it. At Their Peril if they try to Escape!"

Inauthentic picture

But the image is not a genuine depiction of the Florida detention centre, according to satellite images from Google Maps, which depict the location without a moat (archived link).

Pictures taken by AFP photographer Chandan Khanna on July 7, 2025 showing aerial views of the detention facility and its surrounding area also bear no resemblance to the circulated image.

Other media outlets also published photos and footage that do not match the AI-generated image (archived here and here). 

Several visual inconsistencies suggest the image is fabricated, including the shape of the reptiles in the water, making them unlikely to be alligators. 

It also appears that several vehicles have a crumpled appearance, while one of them -- located to the right of the image -- has a misplaced window.

AFP Fact Check analysed the image using the Google SynthID detection tool, which identifies photos and videos generated by its AI models (archived link).

The tool detected that the image was made "with Google AI" with "Very High" confidence.
