US president Barack Obama has created the first national monument to gay rights.
He officially designated the site of the Stonewall riots in Manhattan where the modern gay rights movement took root nearly five decades ago.
The Stonewall National Monument will be in Christopher Park, a small park across from the iconic Stonewall Inn tavern, which covers a 7.7 acre swathe of Greenwich Village where the uprising took place after police raided the gay bar in 1969.
Obama said the monument would "tell the story of our struggle for LGBT rights" and of a civil rights movement that became a part of America.
"I believe our national parks should reflect the full story of our country: the richness and diversity and uniquely American spirit that has always defined us," Obama said.
"That we are stronger together, that out of many, we are one."
To herald the designation, a White House video with photos of the monument is to be played at noon on Saturday on the billboards in Times Square just as New York's annual pride celebration is getting under way.
The declaration also comes as advocates celebrate the one-year anniversary on Sunday of the Supreme Court decision legalising gay marriage nationwide.
Designating the small area marks a major act of national recognition for gay rights advocates and their struggles over the last half-century.
In addition to the Supreme Court decision, since the 1969 uprising the US has enacted anti-discrimination protections, allowed gays and lesbians to serve openly in the US military and seen prominent athletes and entertainers come out.
It also comes as the gay community comes to grips with a fresh and agonising reminder of ongoing threats to their safety.
In announcing the monument, the White House said the mass shooting at a gay bar in Orlando, Florida, illustrated that LGBT people still "face acts of violence, discrimination and hate".
