John Muir National Historic Site

John Muir National Historic Site's spacious and eclectic mansion invites visitors to explore Muir's accomplishments to the National Park Service.

The park preserves the 14-room Victorian mansion where the naturalist John Muir lived from 1890 to his death in 1914. While living in Martinez, Muir accomplished many things: he battled to prevent Yosemite National Park's Hetch Hetchy Valley from being dammed, served as the first president and one of the founders of the Sierra Club, played a prominent role in the creation of several national parks, and wrote hundreds of newspaper and magazine articles and several books expounding on the virtues of conservation and the natural world. Muir's work laid the foundations for the creation of the National Park Service in 1916.
