Datong Mass Grave Memorial, National historical memorial in Datong, China

The Datong Mass Grave Memorial is a national site dedicated to remembering workers who died under forced labor conditions. The complex houses exhibition halls with artifacts, documents, and displays that chronicle the experiences of those who lost their lives.

The memorial commemorates the Second Sino-Japanese War period when thousands of workers perished in the region's coal mines under brutal conditions. The site was established to document and preserve this tragic chapter of history.

The memorial complex includes educational displays and artifacts that document the development of coal mining practices throughout different periods of Chinese history.

The memorial lies at Meiyukou Nangou in the former Datong coal mine area, southwest of the city centre. The two natural caves of the grave site are reached on foot up the north slope; the upper cave is over 40 m long and 5 m wide, the lower one over 70 m long and 4 m wide. The exhibition hall reopened in 2010 after a renovation funded from 2005 with more than 50 million yuan. Allow time for both the caves and the museum.

The entrance bears a pale semicircular panel with three large characters, flanked by vertical inscriptions reading "日寇罪恶千秋恨" on the right and "血海仇深永记心" on the left. Two tilted plaques stand at the lower corners, the left one beginning "语录用". The doorway is cut into rough, fractured stone.
