During World War II Thailand, under Field Marshal Plaek Pibulsongkram, was allied with the Axis powers and declared war on the United Kingdom and United States when the Japanese attacked Pearl Harbor. Bangkok suffered heavily in the subsequent Allied bombing raids and Debsirin School, strategically located near the railway, was not spared. Most of the teaching buildings (Maen Naruemit and Choduek Laohasetthi) were destroyed. They were later rebuilt by the alumni and the Ministry of Education. The main building, renamed "Maen Suksa Stan Building", was built in the Gothic style.
