Roop's Fort, also known as Roop's Trading Post, Fort Defiance, and Roop House, is a historic building in Susanville, California. The building, which was built in 1854 by Isaac Roop, was the first building built by white settlers in Lassen County. The fort was originally a trading post for westbound migrants and was the first post west of Fort Hall in Idaho. The building also served as the capitol of the short-lived Nataqua Territory, a territory created in 1856 to avoid California tax collectors. The territory was incorporated into Roop County, Nevada, named for Isaac Roop, in 1861. California and Nevada entered into a border dispute known as the Sagebrush War over the Susanville area in 1863, and Roop's Fort served as a fort for the Nevadans during the skirmish. California won the war, and Roop's Fort became part of Lassen County in 1864.
It is a California Historical Landmark (#76), and it was listed on the National Register of Historic Places in 1974.
