Located downtown at Fifth and Figueroa Streets and adjacent to the Harbor Freeway, this three-acre paved plaza is situated three stories above the street level and was designed by Garrett Eckbo in 1968. Nestled around the forty-story Union Bank Tower designed by Harrison + Abramowitz of New York and Albert C. Martin Associates of Los Angeles, the plaza was intended to be experienced by pedestrians and to be viewed from above by Union Bank employees. With multiple points of access that include a pedestrian bridge from the neighboring Bonaventure Hotel, a monumental staircase (and elevator) at Fifth Street, and discrete staircases near the freeway, the plaza serves its greater immediate context.

Perhaps inspired by a painting by Joan Miro with its biomorphic and organic forms, the central focal element in the plaza is a series of sculptured islands of water and grass with a central bridge. The water is essentially still with the exception of two small jets. Framing and drawing attention to the fountain are a grove of trees planted on a grid, which corresponds to the structural columns below. The regimented arrangement of the trees transitions from circular concrete planter boxes in the paved center to lawn areas around the perimeter. Tree species include ficus, jacaranda, sycamore and coral. The original design called for a series of sculptural forms by Bella Feldmand which were not realized, but in 1970 the commissioned piece Aquarius by Jerome Kirk was dedicated.
