Mission San Rafael Arcángel was founded in 1817 as a medical asistencia of Mission San Francisco de Asís. It was a hospital to treat sick Native Americans, making it Alta California's first sanitarium. The weather was much better than in San Francisco, which helped the ill get better. It was not intended to be a stand-alone mission, but nevertheless grew and prospered and was granted full mission status on October 19, 1822.HistoryMission San Rafael Arcángel was founded in the present day location of San Rafael, California, on December 14, 1817, by Father Vicente Francisco de Sarría, as a medical asistencia ("sub-mission") of the San Francisco Mission to treat their sick population. It was granted full mission status in 1822.This was one of the second missions turned over to the Mexican government in 1833 after the Mexican secularization act of 1833. In 1840, there were 150 Indians still at the Mission. By 1844, Mission San Rafael Arcángel had been abandoned; what was left of the empty buildings was sold for $8,000 in 1846. The Mission was used by John C. Fremont as his headquarters during the battles to make California a United States possession.On June 28, 1846, three men departed the mission, including Kit Carson, and murdered three unarmed Californians under the order of John C. Fremont; Don José R. Berreyesa, father of José de los Santos Berreyesa, along with the twin sons of Don Francisco de Haro, Ramon and Francisco De Haro.<ref name="http://www.sfgenealogy.com/sf/history/hbbegd.htm group=dab">The Beginnings of San Francisco App. D – The Murder of Berreyesa and the De Haros
