The Siriraj Medical Museum in Bangkok exists because a king's grief demanded it. When King Rama V's infant son died of dysentery in 1888, he channelled his loss into founding Thailand's first permanent hospital on the banks of the Chao Phraya. The museum grew from that institution.

Today, it comprises several collections, of which the forensic wing is the most notorious. Birth defects, stab wounds, tsunami victims, fires, bullet holes: the exhibits are uncensored and, by Western standards, startlingly direct. Among the highlights is the mummified corpse of Thailand's most infamous serial killer and cannibal, as well as a stretch of fence on which someone was fatally impaled, displayed alongside the newspaper clipping.

VoiceMap's self-guided tours approach the museum as part of a deeper journey through Thonburi, tracing Siriraj Hospital's royal origins and situating its confrontational exhibits within Bangkok's history of medicine, monarchy and death.
