The Memorial Museum of Military and Labor Valor was opened on May 6, 1995, in honor of the 50th anniversary of Victory over fascist Germany. Despite its youth, it has become a significant cultural center of the Republic of Mordovia. If you look at the museum's roof from above, you can see that it resembles a map of Mordovia, with a tower in the center shaped like a national kokoshnik, adorned with copper circles reminiscent of medals.

The museum is an important part of the memorial complex "Victory Square" in Saransk. It consists of six halls: "Fiery and Frontline Roads", "Continuity of Generations", a Hall of Fame, a Hall of Commanders, an Exhibition Hall, and a Conference Hall. The grand Hall of Fame is decorated with a mosaic panel dedicated to the memory of front-line soldiers and rear workers. The main exhibition is located in the "Fiery Frontline Roads" hall, where documents, photographs, awards, and personal belongings of local residents who fought on the fronts of the Great Patriotic War are collected, as well as materials about rear workers.

The "Continuity of Generations" hall presents information about the natives of Mordovia who participated in post-war local conflicts, the liquidation of the Chernobyl disaster, and in republican patriotic organizations. The museum maintains connections with the relatives and friends of the deceased, as well as with veterans of the Great Patriotic War. People of different generations bring documents from family archives here.

Part of the museum's exhibition consists of samples of military equipment located around the building. The museum's collections hold over 53,000 items related to the Great Patriotic War and the Republic of Mordovia: documents, archives, weapons, photographs, awards, personal belongings and letters from the front, paintings and sculptures dedicated to the war. On June 5, 2001, a branch of the museum was opened, dedicated to the outstanding Russian poet of the 19th century, native of Mordovia A. I. Polezhaev, located in a restored wooden house No. 51 on Saransk Street, which belonged to merchant Myshkin in the 19th century. Visitors are offered a permanent exhibition, an exhibition hall, city tours, museum classes and lectures, exhibitions, as well as a conference hall for 100 people for events, meetings, conferences, seminars, round tables, and film evenings.
