Built by early settles José María Estudillo and his son José Antonio Estudillo, Casa de Estudillo is an historic adobe in Old Town San Diego that was one of the finest homes of its time. In 1884, Helen Hunt Jackson wrote 'Ramona', a romanticized novel based on the discrimination of Native Americans. It was called the finest novel written by an American woman at the time. It became so popular that people began traveling to California just to see the locations depicted in the book. San Diego capitalized on this influx and renamed the adobe 'Ramona's Marriage Place'.
