Saranrom Park sits in the oldest part of Bangkok, a stone's throw from the Grand Palace. Its central monument marks one of the most quietly devastating stories in Thai royal history.

In 1880, a royal barge carrying one of King Rama V's wives, Sunantha Kumariratana, sprang a leak. She was pregnant and could not swim. Strict royal protocol forbade commoners from touching royalty. No one could help. Bystanders watched as she drowned.

The park began as the grounds of Saranrom Palace, built in 1866 for the younger brother of Rama V. It later served as the Ministry of Foreign Affairs and a residence for diplomatic visitors, before being given to the city in 1960.

VoiceMap's self-guided audio tours pause at the monument to explain the protocol that made Sunantha's death possible, setting it within a broader portrait of palace life, royal hierarchy and the social codes of nineteenth-century Siam.
