It includes a circular enclosure, maze entryway paved with mosaic tiles, ten large sculptures, and native trees and shrubs planted both inside the plaza and around the outer wall.

[1] The 120-foot diameter enclosed garden is part of a 12-acre (4.9 ha) habitat in Kit Carson Park's Iris Sankey Arboretum, and was opened to the public on October 26, 2003.

[3] Queen Califia’s Magical Circle is known as the only American sculpture garden, and the last major international project created by Niki de Saint Phalle before her death in 2002.

[3] The installation showcases the artist's signature designs such as voluptuous female figures, hybrid creatures, and mythical symbols that are covered in vibrant mosaic.

[6] The artist was inspired by reading of this legend in Assembling California, a book by Pulitzer Prize winner John McPhee, which described the geologic history of the Golden State.

[7] In the center of the garden is an 11-foot (3.4 m) mosaic sculpture of Queen Califia in gold glass armor, standing atop a 13-foot (4.0 m) eagle and raising a small bird above her head.

[3][7] In the middle of the plaza is a golden egg-shaped fountain, which represents both Califia's magical reign over the sea and the birth-death-transformation cycle that serves as a recurring theme in Saint Phalle's works.
