Sherman Quarters, Historic adobe building in Downtown Monterey, United States.

Sherman Quarters is a one-story adobe structure with a fieldstone foundation, painted earthen plaster, and wooden shutters that shows early California building methods. The roof is shingled and the building features a covered porch that connects the interior spaces to the garden area outside.

Thomas O. Larkin built this small adobe in 1834 on his Calle Principal property, next to the Larkin House. From 1847 to 1849 it served as headquarters for Lieutenant William Tecumseh Sherman and military secretary of state Henry W. Halleck, serving under Colonel Richard Barnes Mason, military governor of California. Sherman later became a Union general in the American Civil War.

The building shows how early California residents built their living spaces using earthen bricks and simple wooden elements that suited the local climate. You can still see this hands-on construction approach in the walls and the covered porch that opens toward the courtyard.

The building sits adjacent to the Larkin House and is visible from the public pathway. Visitors can best explore the exterior architecture and building details by walking around the surrounding streets and garden areas.

The spiked cannon standing in front of the house was used as a hitching post. The building also carries a legend: Sherman was said to have fallen in love with Señorita Maria Ygnacia Bonifacio, who lived there before his 1847 posting, and gave her a rose-tree, the "Sherman Rose," promising to return.
