A ceremony will be held for the Prospect Park Pavilion that opened originally in 1891.
Parks and Recreation Director Eric Griffith calls the park and pavilion one of the crown jewels of the city's park system.
"It's one of the oldest parks in our area and even though the park has changed substantially over time but this building has been there. So it's important to our story and our legacy as a city."
It was first considered for landmark status in 2017 but final approval was postponed until renovations could be completed.
The ceremony will be held at 2 pm Friday, in Prospect Park.
