The Diego Sepúlveda Adobe, sometimes called the Costa Mesa Estancia or the Santa Ana Estancia, is an adobe structure in Costa Mesa, Orange County, California.[2] [3] It is the second-oldest building still standing in the county.
The adobe was built between 1817 and 1823 to house the mayordomo and herdsmen who tended the cattle and horses from Mission San Juan Capistrano to the south, in Alta California. The way-station was strategically situated on the banks of the Santa Ana River, some six leguas (Spanish Leagues) north of the parent mission, to overlook cattle grazing lands and the Tongva villagers of Lupukngna.[4]
It served as a lookout post when the French privateer Hippolyte de Bouchard attacked San Juan Capistrano on December 14, 1818. By 1820 the building and its surrounding lands became an official estancia (mission station), where padres from the mission would visit regularly to bring "spiritual food" to the faithful.[5]
After the Mexican secularization act of 1833 the church lost the land and building to the originally Spanish, later Mexican-recognized land grant Rancho Santiago de Santa Ana. The adobe and its surrounding property, a portion of Rancho Santiago de Santa Ana, were deeded by the U.S. government to Diego Sepúlveda around 1868. He was a former alcalde of the Mexican era Pueblo of Los Angeles.[3]
The adobe, which has been restored to its original style using original construction methods, is the second-oldest building still standing in Orange County.[2] The Mission San Juan Capistrano's "Serra's Chapel" is the oldest.
The building then became a local history museum, operated by the Costa Mesa Historical Society.[2] [3]
