Lake County Historic Courthouse Museum

Lake County Historic Courthouse Museum

Located in Lakeport, this brick courthouse, completed in 1871, was the first courthouse in California to be placed on the National Register of Historic Places in 1970; later it was dedicated as a museum in 1978.

Nearly 12,000 years ago, the Xa-Ben-Na-Po Band of Pomo Indians—whose descendants still live here today—called Lake County home, as well as Wintun, Wappo, and Lake Miwok Indians. Thousands of stone tools and more than 300 superb examples of Pomo basketry have been acquired by the museum since the 1930s. The main gallery of the museum showcases many artifacts and displays of Pomo culture.

In 1897, famous British actress and socialite Lillie Langtry, who purchased Langtry Estate & Vineyards in the 1870s, received her divorce in this courtroom. In 1917, a landmark California Supreme Court case was decided here. Ethan Anderson, a Lake County Native American, became the first Native American in the United States to win the right to vote.

Learn about the early days of hunting and camping in Lake County with some very special firearms on display. Of special interest is “Old Fremont,” a Revolutionary War rifle that made its way across the plains with the Hammack party from Missouri in 1853.

Permanent exhibits include the Victorian Parlor, which takes the visitor back to a bygone era; the Rock and Mineral Room, which features a 94-carat faceted Lake County Diamond; the History and Mystery of Clear Lake, which tells the story of the ancient lake; and numerous changing exhibits that highlight Lake County’s past.
