Lassen Historical Museum and Roop's Fort

The Lassen Historical Museum is located near Memorial Park and directly next to the historic Roop's Fort, the oldest building in Lassen County. Run by volunteers and board members of the Lassen County Historical Society, the Museum has gone through a series of transformations over the years, including renovation of the building it currently occupies next to Roop's Fort.  The renovated building now acts as the prime location for historic displays about the history of Susanville, Lassen County and the region.  Exhibits are refreshed and added frequently.

About this Establishment

Whereas Roop's Fort is one of the most culturally significant buildings in the entire Lassen County, it is also home to many historic items from previous centuries including authentic arrowhead collections and Native American art, to the last remaining pieces of historic uptown businesses that have long since vanished.  Here you can see old weapons, bottles, photographs and more from the County's founding fathers.  Taking time to discover some of the Museum's myriad treasures will truly be rewarding. And, don't forget to check out the oldest building in the County right next door, Roop's Fort, which has stood on this site since 1854 when it originally served as a trading post for early emigrants.

The Lassen Historical Museum and Roop's Fort are located near Memorial Park at 75 North Weatherlow Street in Susanville.

As a descendant of Roop, I'm definitely biased, but the museum is a gem, in my view, with its changing exhibits. It has a cozy fireplace and rocking chair, just a nice size to see in an hour or two. They also sell local historical books, postcards and handmade items. You'll get a warm greeting from a docent who is knowledgeable about local history.

Am looking for information. My great-grandfather Henry Clay Stockton laid the town out for Mr. Roop, and built a lumber mill outside the town. I have pictures of the property when I visited as a baby and a picture taken from above. Do you have any information on the mill, and how large was the property. He manufactured and delivered all the lumber to build Reno, hauling it over the Sierras with a 16 yoke oxen team [32 oxen]. Any help you can give me would be appreciated.

I am writing an article about the Herlong USO during World War II. If anyone has any information or suggestions, I would very much appreciate any leads. Thanks so much!

I'm trying to find the EXACT location of Fort Sage. Does anybody have any shred of information..? Geographic Coordinates..? I've researched military archives, and also asked somebody at the Herlong School (at the Sierra Army Depot) but this info seems to be lost. Thanks..

Looking for anybody who remembers the Kellers shoe shop in Susanville.

My grandfather, John Polk Matkin, worked for Fruit Growers from around 1913 until his death in 1927. He was a master machinist and built a working 1/10th scale model of a gasoline tractor. It was sent to a manufacturer that built a full size one based on the model. I would appreciate leads to photos and/or info concerning his activities in Susanville. Gerald Matkin

One of my VA work study volunteers as Veterans Service Office told me back in the early ’80's that he found (and presumably stole) a 33 star US Flag. The flag was of an unusual design. I never saw the flag so I didn't report it. I do know who that was.

This museum is well worth your visit. As an educator (currently a principal in WA state but a long history in the Bay Area of CA) I am always interested in the school systems history. Learn about the Camels and the sports teams and see the pictures of the children. I will return.
