Hastings about one-third mile north of Collinsville, Solano County, California, later enclosed by a frame structure.","why_significant":"The adobe was built by Hastings, a Mormon agent, as the centre of a planned colony and city called Montezuma City at the junction of the Sacramento and San Joaquin rivers. The plan faded when the American flag was raised in California on July 7, 1846. The house later served as a ranch dwelling for the Marshall and Stratton families.","narrative":"Built in 1846 near Collinsville in Solano County, this adobe house was erected by Lansford W. Hastings, an Ohio lawyer who had written an emigrant's guide to California and was named a Mormon agent to choose a colony site. He selected land where the Sacramento and San Joaquin rivers meet Suisun Bay, planned a city called Montezuma City, and built the four-room adobe with an attic from sun-dried bricks of local clay and river water. The American flag was raised in California on July 7, 1846, and the Mormons lost interest in the site. Hastings left after about three years. L.P. Marshall and his sons occupied the house from 1853, and the family held it until 1908, when the Stratton family acquired it. A frame structure was built around the adobe. Pacific Gas & Electric bought the property in 1963 as a future power plant site. The building is now idle, damaged by vandals and rain, and fenced.","period_of_significance":"19th Century; prior to July 7, 1846","architect_builder":"Lansford W.
