John Muir National Historic Site
Why it's listed
John Muir National Historic Site in Martinez, California, preserves the home and ranch buildings where the naturalist and writer lived and worked. The main building is a two-story wood frame house of 1882-3, designed by Wolfe & Son of San Francisco in the Victorian Italianate style, with a cupola, oriel windows and quoins. Nearby are a Carriage House and the Martinez Adobe, a two-story rancho building probably built in 1849. Muir wrote most of his work in the second-floor study of the house and met there with other conservation leaders. The nomination credits him with major influence on the creation of national parks and forest reserves, and with describing the glacial origins of Yosemite Valley. It also notes the plantings of more than 120 plant varieties begun by Muir and his father-in-law, Dr. John Strentzel. The federal government acquired the property in 1964 as a memorial to Muir.
Significance in brief: The site is argued to be of national significance in conservation, literature, science and social/humanitarian concerns because of John Muir's work to establish national parks and to bring his nature experiences to the public through writing. It is of regional significance in agriculture and architecture, for a late Victorian country house and a California-Mexican rancho adobe, and for plantings by Muir and his father-in-law.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved.
