Hagemann Ranch Historic District

Hagemann Ranch is a five-acre farmstead on Olivina Avenue in Livermore, about a mile and a half west of downtown and now surrounded by suburban housing. Its single-story wood-frame farmhouse likely began as a cabin built around 1870 by Martin Mendenhall, and it grew in phases under Mendenhall and later the Hagemann family, with additions in 1910, 1920 and 1948. Eleven outbuildings and structures line a central east-west farm lane, including horse and cow barns, a blacksmith shop, a granary, chicken coops, a garage and a windmill pump house. Mature oaks and eucalyptus trees add to the setting. The property is significant for representing the farming life of the Livermore Valley from 1870 to 1930. It is recognized for architecture as a collection of vernacular farm buildings that remain largely intact, and it conveys a strong sense of nineteenth-century agriculture despite the loss of most of its original acreage.
