[1] It is the second park in a series of urban open spaces designed by American landscape architect Lawrence Halprin in the South Auditorium District urban renewal area.

The park is characterized by a dense tree canopy which shades a core of internal asphalt pathways pivoting along grassy berms and basalt stone walls.

At the southeast corner of the park, a reflecting pool and sculpture serve as a focal point for pedestrians.

[1] The park was named for Francis Pettygrove, one of the early settlers of the Portland townsite.

The same coin used by Pettygrove and settler Asa Lovejoy to determine whether the city would be named Portland or Boston was flipped to determine which park in the open-space sequence would be Lovejoy and which would be Pettygrove.
