Sitting atop a bluff overlooking the Santa Ana River, sits an old adobe that previously was used to house cattle ranchers. This adobe was built around the early 1820's on an estancia (large plot of land used for farming). The park that this adobe sits on is named "Estancia Park" after its history. This land was originally used by the Natives but after the Spanish took it over was when the need for an adobe came in. The Segerstrom family purchased the adobe in an effort to preserve its history in the area.
