Constructed in 1825 as the home of Don Jose Antonio de Estudillo, a Spanish aristocrat. It became a sanctuary for women and children during the American occupation in 1846. For a number of years it was incorrectly identified as "Ramona's Marriage Place" from Helen Hunt Jackson's "Ramona". The adobe structure is considered to be one of Old Town's outstanding show places.

La Casa de Estudillo was turned over to a caretaker in 1887 who sold its tiles, locks, doors and windows. In 1910 architect Hazel W. Waterman supervised the restoration of the house with funds provided by the Spreckels family.
