On June 12, 2016, 29-year-old Omar Mateen killed 49 people and wounded 58 others in a mass shooting.
The attack was the deadliest single gunman mass shooting in United States history until the 2017 Las Vegas shooting, the deadliest incident of violence against LGBT people in U.S. history, and the second deadliest terrorist attack on U.S. soil since the September 11 attacks of 2001.

In November 2016, the city of Orlando agreed to buy the nightclub for $2.25 million.
Mayor Buddy Dyer expressed plans to convert the nightclub into a memorial to honor the memory of the victims.

Barbara Poma, the owner, refused to sell the nightclub to the city in December 2016.
Instead she announced in May 2017 the creation of the onePULSE Foundation to independently fund a memorial site and museum slated to open in 2022.
