The 1938 Great Fire of Changsha is the event that most shaped the city's current appearance. On 12 November 1938, with Japanese forces advancing from the north, Chinese military commanders ordered the city set alight to prevent its capture intact. The fire burned for three days, destroying most of the historic urban fabric — the old merchant streets, the temples, the guild halls, the traditional courtyard houses. An estimated three thousand to five thousand residents died; up to ninety percent of the city was destroyed. The Japanese army arrived eighty kilometres away when the fire began.
The memorial site near the old city centre covers this event and its aftermath, documenting both the decision-making that led to the fire and the city's reconstruction. The exhibition is unsentimental and does not spare the Chinese military leadership responsible; it is one of the more honest official historical presentations in China. Understanding the 1938 fire explains why so little of pre-modern Changsha survives despite the city's age: the heritage streets visible today are largely twentieth-century reconstructions.
