Feb. 10 (UPI) -- The National Park Service removed a Pride flag from the Stonewall National Monument in New York City.

The monument is in Greenwich Village, and it commemorates the Stonewall Inn, a Manhattan gay bar that was the epicenter of the 1969 Stonewall riots. The Stonewall uprising kicked off a new battle for gay rights.

Former President Barack Obama made Christopher Park, across the street from the bar, a national monument in 2016. The NPS has flown Pride flags since it became a monument.

A spokesperson for the parks service cited new rules requiring that "only the U.S. flag and other congressionally or departmentally authorized flags are flown on NPS-managed flagpoles, with limited exceptions," the spokesperson told NBC News. "Any changes to flag displays are made to ensure consistency with that guidance. Stonewall National Monument continues to preserve and interpret the site's historic significance through exhibits and programs."
