In 1913, a significant but now almost forgotten event took place, the Exhibition of the Priamur Region. This year was special for Russia and Khabarovsk, marking the 300th anniversary of the Romanov dynasty and the 55th anniversary of the city. At the initiative of Governor-General Gondatti, a large-scale exhibition was organized to showcase the achievements of various sectors in the Priamur Region. Officially named "Exhibition of the Priamur Region in Commemoration of the 300th Anniversary of the Romanov House," it was located in the area of the modern "Dynamo" park, covering about 26 hectares.

The exhibition resembled a small town built in the neo-Russian style, where each building was unique. For example, the entrance to the Amur Railway pavilion was designed like an arched tunnel, creating the impression of passing through the gates of a station.

Two unusual pavilions attracted special attention. One was a kiosk located inside a huge tree stump with a slanted cut, where cigarettes and soft drinks were sold. Its size allowed several people to be inside at the same time. The other pavilion, resembling a large champagne bottle, belonged to merchant Laskov, a well-known trader of wine and spirits.

The main pavilion of the exhibition housed nine main sections: scientific and educational, ethnographic, medicine and veterinary, arts and photography, municipal affairs, Red Cross society, communications and telegraph, as well as mining.

Since its opening on July 15, 1913, and over two months of operation, the exhibition was visited by about 110,550 people, which was a significant number for that time. The popularity of the exhibition is also confirmed by the wide participation: applications for the construction of pavilions in Khabarovsk came from France, Italy, the USA, Australia, and other countries.
