The Gardner Heist was one of the most daring art thefts in history, with an estimated $500 million worth of masterpieces stolen from Boston's Isabella Stewart Gardner Museum. In April 1990, two men disguised as police officers burst into the museum during a charity gala, taking 13 works of art, including paintings by Rembrandt and Vermeer, Monet and Degas, among others.

The heist remains one of the most infamous in museum history, with no leads or suspects. The artworks were later discovered to have been hidden under floorboards in a storage room. Despite extensive investigations, no one has been convicted of the crime. The case is still unsolved, leaving behind only fragments of evidence and speculation.

The Gardner Heist was a brazen crime that shook the art world and raised questions about the security measures in place at institutions with valuable collections. The mystery surrounding this heist continues to captivate and intrigue art lovers to this day, inspiring countless books, documentaries, and even a stage play.
