It is also tied to Henry Rengstorff, a leading pioneer and businessman who ran a major bayside shipping landing and donated land for the town's first school.","narrative":"This 16-room house at 1737 Stierlin Road in Mountain View was built around 1867-1868 for Henry Rengstorff, a pioneer farmer and businessman who bought the land in 1864 and lived there until his death in 1906. Its symmetrical front has a pillared portico, a pediment, bay windows, brackets, cornices and quoined corners, with Italianate, Georgian and classical elements. It is described as the oldest known existing building in Mountain View. Rengstorff farmed extensively, owned barges and operated a bayside landing that shipped grain, hay and lumber, and he donated land for the town's first school. By the time of listing the house stood vacant. The windows were boarded, the widow's walk removed and the interior vandalized, but the slate roof and basic structure survived. Its location in a flood plain and developing industrial area led to study of moving it into Shoreline Regional Park for museum or interpretive use. The State had designated it a Point of Historical Interest.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Italianate, with Georgian Neo-Classical overtones","criteria":[],"status_note":"Vacant and unoccupied.
