In 30 years of 19th century the objects from the museum were transmitted to Odessa, Kherson and Kerch, and only a small part of the exhibits remained in Mykolaiv Region.

In February 1912, the descendants of Emmanuel Frantsov who died in 1909 and who was the owner of the unique natural science collections approached to the council of Mykolaiv.

[2] On Sunday, 15 December 1913, during the opening ceremony of the museum Mayor M. Leontovich, the representatives of the city's Duma and numerous guests were presented.

[3] After the opening, a lot of things had changed: the funds had received new items of archeology, interesting documentary sources, photographs, weapons, objects of ethnography and numismatics.

The financial book for the years 1913–1916, which is stored in the archives of the museum, contained the bills and receipts with the list of purchased items.

In 1916 – 1917, S. I. Gaiduchenko together with A. D. Petraschuk traveled to the Grand Duke Mykola Mykolajovych estate to the Katerynoslav province.

From that place they brought the Cossack overgrave cross, "stone women", archeological items, stuffed birds and animals.

Despite the rough events of the February Revolution and the Civil War the museum continued to develop.

After the death of S. I. Gaiduchenko, F. T. Kaminsky – archaeologist, expert on the history of the land, popularizer of the ancient monuments – became the director of the museum (May 1923).

But six months later, the museum's director, tireless researcher F. T. Kaminsky, was accused for being a member of the Union for the Freedom of Ukraine process, and had been in Joseph Stalin's camps for 25 years.

The museum was required by the citizens who survived after a terrible war and did not lose interest to the history and nature of native land.

Here the items from the famous collection of E. P. Frantsova were displayed: minerals, corals, stuffed animals, birds, fish and even a few anomalies.

Today, Mykolayiv Regional Museum of Local History “Staroflotski Barracks” is often visited.

The significant contribution to the Mykolaiv museum was made by Liudmyla Hlopynska, an honored worker of the Ukraine's culture, a laureate of the Shevchenko National Prize.
