In 1894, the imperial (tsardom) pavilion was built for the arrival of imperial persons in the city. The architect Dmitry Chichagov, a representative of the famous dynasty of Russian architects, designed both the building and the interiors. The hall of the pavilion was decorated with a large portrait of Nicholas II and a carved fireplace made of white Italian marble. A telephone was installed for important talks. The pavilion received the emperor twice: in 1896, during the All-Russia Exhibition and in 1913, during the celebration of the Romanov Tercentenary. During the 1905 revolution, it was captured by rebellious workers and held for some time. After the October Revolution of 1917, the Committee of the Bolsheviks of Kanavino and the medical institution of railway were located in the building at different times.
