The Krasnoarmeysky Museum was opened in 1987 as a public museum dedicated to revolutionary, military, and labor glory. It is located in a one-story brick building built in the early 20th century. In January 1990, the museum became a branch of the Saratov Regional Museum of Local Lore, and since 1997 it has been named the Krasnoarmeysky Local History Museum. The museum building, which was previously a residential house of a prosperous Volga German from the late 19th and early 20th centuries, is made of wood and faced with characteristic red two-colored brick. The founder of the museum is Tamara Petrovna Weis.

The museum's collections include ethnographic items, decorative and applied arts, ceramics by masters from the village of Zolotoye from the early 20th century, as well as documents and photographs from the late 19th and 20th centuries. The exhibitions and displays introduce visitors to the history, culture, and economy of the city of Krasnoarmeysk and the district of the same name from the 18th century to the present day. Special attention is paid to the coexistence of Russians and Germans in the area from the mid-18th century to 1941, as well as the main occupations and crafts, the history of weaving and knitting industries that grew from the sarpino weaving craft.

In November 1987, at the initiative of the district leadership, the Public Museum of Revolutionary, Military, and Labor Glory was opened in Krasnoarmeysk. It was housed in a building that belonged to a wealthy family of Volga Germans until the 1920s. The museum's exhibition included three main sections: the Hall of the History of the Revolution and the Civil War, the Hall of the Great Patriotic War, and the Hall of Labor Glory. One of the rooms was allocated for the Exhibition Hall.

In March 1990, the museum became a branch of the Saratov Regional Museum of Local Lore. In the 1990s, the themes of the museum's research work expanded: the study of the history of German villages in the district, the ethnography of Russians and Germans, key events in the region's history from the 17th to the early 20th century, as well as a deeper exploration of the district's history in the first half of the 20th century began. New thematic sections were added to the permanent exhibition: the History of the Volga Germans, the settlement of the area by immigrants from Germany in the 18th century, the district as part of the ASSR of the NPA, crafts and everyday life of the Volga Germans, World War I in the history of the district, collectivization and repression of the 1930s-1940s, the establishment of light industry and machine engineering enterprises based on artisanal workshops, the history of the modern district, and many others. Various exhibitions from the museum's own collections are held in the Exhibition Hall, such as "History in the Past Days," "A Resonant String in the Soul," "Secrets of Ancient Treasures," "Golden Hands of Masters," as well as exhibitions of children's creativity and works by local artists and masters of decorative and applied arts.

In 1998, the museum was renamed the Krasnoarmeysky Local History Museum. Today, it serves as a cultural and intellectual center of the district, hosting significant events, award ceremonies, seminars, conferences for education and culture workers, meetings with interesting people, and honoring veterans of the Great Patriotic War and labor.

From its founding until 2006, the museum was headed by T.P. Weis, the oldest cultural worker in the district, whose experience in cultural institutions in Krasnoarmeysk spans nearly sixty years.

The museum's educational programs include a series of intellectual local history games: "Forward to the Past," consisting of stages with questions and tasks on the history and ethnography of the district; "We Remember and Are Proud," dedicated to the history of the Great Patriotic War and the district during this period; "Fun and Games for Entertainment and Understanding," a game with a quiz and ethnographic elements; "Christmas in the Museum," including ancient folk games and divinations; and an interactive session "Golden Hands of Masters," dedicated to the main occupations and crafts of the local population in the 18th and early 20th centuries.
