President Obama is poised to declare the first-ever national monument recognizing the struggle for gay rights, singling out a sliver of green space and part of the surrounding Greenwich Village neighborhood as the birthplace of America’s modern gay liberation movement.

While most national monuments have highlighted iconic wild landscapes or historic sites from centuries ago, this reflects the country’s diversity of terrain and peoples in a different vein: It would be the first national monument anchored by a dive bar and surrounded by a warren of narrow streets that long has been regarded the historic center of gay cultural life in New York City.

Federal officials, including Interior Secretary Sally Jewell, National Park Service Director Jonathan B. Jarvis and Rep. Jerrold Nadler, D-New York, will hold a listening session on May 9 to solicit feedback on the proposal. Barring a last-minute complication – city officials are still investigating the history of the land title – Obama is prepared to designate the area part of the National Park Service as soon as next month, which commemorates gay pride.

Protests at the site, which lasted for several days, began in the early morning of June 28, 1969 after police raided the Stonewall Inn, which was frequented by gay men. While patrons of the bar, which is still in operation today, had complied in the past with these crackdowns, that time it sparked a spontaneous riot by bystanders and those who had been detained.

Although national monument designations are partly symbolic, backers of the move said it could bolster the fight against discrimination based on sexual orientation and gender identity, which led to the landmark 2015 Supreme Court ruling legalizing same-sex marriage.

“We must ensure that we never forget the legacy of Stonewall, the history of discrimination against the LGBT community, or the impassioned individuals who have fought to overcome it,” Nadler, who has co-authored legislation that would make it a national park, said in a statement. “The LGBT civil rights movement launched at Stonewall is woven into American history, and it is time our National Park system reflected that reality.”

The president has described Stonewall as a critical event along the nation’s path to become “a more perfect union,” both in his second inaugural speech and when celebrating the 50th anniversary of the march on Selma, Ala.

Interior Department spokeswoman Amanda Degroff said Obama “has made clear that he’s committed to ensuring our national parks, monuments and public lands help Americans better understand the places and stories that make this nation great” – though at the moment the administration has no official announcement on the designation.

In a sign of how much has changed since 1969, the three officials who represent the area — City Council member Corey Johnson, state assembly member Deborah Glick and state senator Brad Hoylman — are all openly gay and endorse the idea of making it a monument, as does the local community advisory board.
