The Hayes Mansion

Mary Hayes Chynoweth, matriarch of the Hayes family, built this 65 room, 41,000 square foot Mediterranean Revival-Style mansion to replace an earlier Victorian one which had been destroyed by fire. While she did not live to occupy the mansion herself, her two sons and their families lived in the house for four decades.

Everis Anson Hayes and Jay Orley Hayes were two of San Jose’s most influential and illustrious citizens. E.A. Hayes served in the U.S. House of Representatives from 1904 to 1918. J.O. Hayes was founder and president of the California Prune and Apricot Growers Association, which later became known as Sunsweet Growers. Together the two brothers owned and published the San Jose Mercury and the San Jose Herald Newspapers.

The Edenvale Estate was a center of social and political activity for the Santa Clara Valley and was visited by many distinguished public figures.

The Hayes Mansion was designed by architect George Page and completed in 1905. Renovation and remodeling was completed in 1994 by the public/private partnership of the City of San Jose and the Renaissance Conference Company.
