Liam Enea, 19, stumbled upon the images as he was flipping through an old Valentine's Day-themed album that once belonged to his great-aunt Maryann Puglisi-Muñoz.

Enea said he was able to locate the building from which his great-aunt took the pictures.

"Through the photos, I determined that she lived in an apartment at 310 Greenwich Street in New York City whose terrace faced south toward the World Trade Center," said Enea. 

"On that day and in the aftermath, she took the photographs on a type of disposable camera. I determined that she lived there by looking at an aerial photograph of the buildings and locating the nearest residential high-rise north of the towers. Also, when I showed my mother the building, she instantly recognized it from a 1990s visit and confirmed that Maryann lived there."

The album was initially given to Enea's late grandmother by Puglisi-Muñoz, and it was passed down to him around four years ago. Enea scanned the images in February of this year and posted them on a TikTok video on Sunday.

Enea also shared the images on Reddit, garnering thousands of likes.

"I was compelled to post them on Reddit because I hoped people would find them interesting, given that the most iconic photos of the events were taken from a distance, on the ground near the buildings, or from the sky. These photos show the towers from a close residence," said the teen.
