Palomares, Ygnacio, Adobe
Why it's listed
Set in a 20-acre park facing Arrow Highway in Pomona, this one-story adobe was built around 1854 as the residence of Don Ignacio Palomares, who had obtained Rancho San Jose de Arriba in 1837. He also built an earlier house in 1837, which still stands. The 1854 building has thick adobe walls and a shake roof, and it is regarded as a fine example of a ranchero's home. Besides serving as the family residence, it became a popular stage station and tavern. For many years it stood deserted and neglected until it was restored, with work recorded in 1939, and opened to visitors by the Historical Society of Pomona Valley. Some changes from the original exist, but they remain within the early period design. Today it is furnished and open to the public, and it is described as one of the finest examples of its kind in California. It is also designated California Historical Landmark #372.
Significance in brief: The adobe was the home of Don Ignacio Palomares, who obtained Rancho San Jose de Arriba in 1837, and it later served as a popular stage station and tavern. After years of neglect it was restored and opened by the Historical Society of Pomona Valley. The nomination calls it one of the finest examples of its kind in California.
