Weimar (formerly, "New England Mills" or "Weimer") is an unincorporated community in Placer County, California,[1] located in the Sacramento area.

[3] In April, 1919, in the wake of the end of World War I, a resolution was introduced in the California State Senate to change the town's name to Argonne.

The resolution was defeated after the local senator insisted the name was not German, but actually came from Weimah, a chief of the Grass Valley tribe of Southern Paiute Native Americans, who had been hospitable to the area's first white settlers.

[4] By car, Weimar is about 80 minutes from Reno, Nevada and about one hour northeast of Sacramento, California on east I-80.

Snow in Weimar occasionally falls due to its higher latitude, averaging 10.2 inches or 0.259 metres per year, mostly in winter months.

Weimar's Köppen classification and climate similarities to locations such as Napa, California and parts of Italy make it a suitable region for growing wine grapes.
