This article explores how purpose-built museums interpret the story of colonial imprisonment in Ho Chi Minh City, Vietnam. Prisons integral to the 100-year French colonial occupation, and the subsequent American War, have been re-purposed, destroyed, or obscured. In response, memorial museums have an important role presenting prison history to international tourists and local visitors alike. Our approach interprets artefacts relating to restraint and torture, the reconstruction of prison cells, and the use of photography in three museums in the city-the War Remnants Museum, the Ton Duc Thang Museum, and the Museum of Southern Vietnamese Women-each featuring recreations of the Tiger Cages from a further notorious prison site, some 200 kilometres southeast of HCMC on the Côn Đảo archipelago. Memoirs, photographs, objects, and plaques from prisons in HCMC and Côn Đảo offer domestic and international tourists narratives stories of Vietnamese resistance to imprisonment. Considering the way former prison sites and museums memorialising prisons can be taken together as a series, we use the concept of the "penalscape" to indicate the contextual links between prison, education, and political struggle in an abolitionist framework.
