The Decembrists Museum is located in a two-story mansion that belonged to merchant Dmitry Starcev, a close friend of brothers Nikolai and Mikhail Bestuzhev. The museum opened in 1975, timed to the anniversary of the uprising in St. Petersburg.

At the entrance to the museum stands a monument to Nikolai Bestuzhev, and a memorial plaque with shackles and portraits of the brothers is mounted on the building, which reads: "In this house in 1840 and 1860, the Decembrists brothers N.A. and M.A. Bestuzhev, K.P. Torson, who lived in exile in Selenginsk, visited."

On the way to Starcev's mansion, there is an arch dedicated to the Selenginsk Infantry Regiment. By prior arrangement, a meeting of a tourist group with Cossacks, their songs, and rituals can be organized. After the arch, cannons and an information stand telling about the regiment's combat path are set up on the right.

The mansion, which now houses the museum, was built in the 19th century and has two floors with columns. Inside, there are eleven halls, starting the tour from the second floor, which is accessed by a steep staircase.

The first thing that catches the eye is the wooden sculptural portraits of the Bestuzhev brothers, created by the honored artist of Russia G.G. Vasilyev, and a bas-relief depicting the executed Decembrists.

To the right are halls dedicated to the Patriotic War of 1812 and the life of the country before the events on Senate Square. Here, household items of peasants and tin figurines of soldiers from the 41st Infantry Selenginsk Regiment are presented.

The next halls tell about the life of the Decembrists in exile and in Buryatia. Here, one can see real shackles, products made by prisoners of the Petrovsky factory, and portraits of former inmates.

Visitors then descend slightly and pass under a low arch, where a diorama by artist A.I. Korentsov is located. Attention is drawn to a wooden cross from the late 17th century and figures of saints, in the creation of which, scholars believe, Nikolai Bestuzhev participated.

The exhibition continues on the first floor. After passing through the souvenir shop, guests enter a hall dedicated to the ancient city of Kyakhta, where the Bestuzhevs often visited.

Then visitors move to the seventh hall, which tells about the activities of the Decembrists after their exile.

The eighth hall presents items belonging to the Bestuzhevs, including gifts from relatives. The ninth hall is the study of the house owner, D.D. Starcev, with antique furniture.

In the living room, the penultimate hall, evenings and salons were held, and they played the piano. The eleventh exhibition is dedicated to Buryatia, where one can see masks, household items, and clothing of the local people.

In addition to the museum tour, tourists can visit Mount Anglichanka, which offers a view of the Posadskaya Valley and the Selenga River, as well as learn about the activities of English missionaries in Buryatia and old Selenginsk.

A special impression is made by the necropolis, where Konstantin Torson and his mother Charlotte, Nikolai Bestuzhev, and the wife and son of Mikhail Bestuzhev are buried. The crosses and gravestones were made according to the project of Mikhail Alexandrovich, with restorations carried out in 1959 and 1974. The column symbolizes clasped hands, and the bas-reliefs depict scenes of the uprising, imprisonment, and life in exile. The necropolis is surrounded by a fence, with trees growing at the entrance and a gazebo installed.

The Decembrists left a significant mark in the history of Buryatia, contributing to the development of the region, which is why they are treated with respect and efforts are made to convey these feelings to tourists visiting the museum.

The museum can organize theatrical performances upon request, where actors in costumes introduce visitors to life in Selenginsk and read lines from A.S. Pushkin's poem "In Siberia," dedicated to his comrades in exile.
