The San Bernardino de Sena Estancia was a ranch outpost of Mission San Gabriel Arcángel in what is now Redlands, California, United States. It was built to graze cattle, and for Indian reductions of the Serrano people and Cahuilla people into Mission Indians. Over time, it fell into disrepair, until the early 20th century, when a new, larger structure was built as a museum. The new structure shares the same architectural style, but is not otherwise similar to the original buildings.

Mission San Gabriel Arcángel is a Californian mission and historic landmark in San Gabriel, California. It was founded by the Spanish Empire on "The Feast of the Birth of Mary," September 8, 1771, as the fourth of what would become twenty-one Spanish missions in California. San Gabriel Arcángel was named after the Archangel Gabriel and often referred to as the "Godmother of the Pueblo of Los Angeles."
