In 1941, the building housed a military hospital. While retreating from the city, the fascists burned the building of the former male gymnasium along with other houses. All that remained of it - burnt brick walls - was transferred to the industrial technical school. Reconstruction work was completed in 1952.
This hospital was built at the soda factory and located in the "Belgian heritage," the conventional name of a residential quarter in Lysychansk, which consisted of residential and public buildings erected at the end of the 19th - beginning of the 20th century for the servants and workers.
