History

[edit]

Bloomfield is located on part of Rancho Cañada de Pogolimi. In 1853, William Zellhardt built a house on the site of present-day Bloomfield, which attracted other immigrants and led to plans for a town in 1856. At one point in the late 1850s, Bloomfield was the second largest town in Sonoma County, and in 1877 it had four hotels and a population of 250. However, the town never recovered from being bypassed by the railroads, and its growth tapered off.[4]
