The final stage of Washington Square Park's $30 million-plus restoration is now complete.
City officials joined elementary school students for a ribbon-cutting ceremony to mark the occasion.
The latest stage in the project includes the opening of a large dog run, a new playground and a park house with public restrooms.
Some of the features of the first two stages of the project were expanding the park's green space and creating new seating areas.
"This project is very much in keeping with Mayor de Blasio's mission to increase the sustainability of city buildings, improve access to our parks and bring our neighborhoods closer together," said Feniosky Peña-Mora, commissioner of the Department of Construction and Design.
"I know these additions to the park, along with the previous two phases, will combine to create a fantastic experience for all the park visitors," said City Councilwoman Margaret Chin of Manhattan.
The Department of Parks and Recreation says additional work to restore perimeter sidewalks will begin this winter.
