The French used the upper level of the prison to keep chickens, intentionally allowing waste to drop onto prisoners held below as a form of psychological and physical torture.
The structure was built during the French occupation of Chanthaburi, which lasted 11 years from 1893 to 1904.
The prison is constructed from red brick, a distinct architectural choice of the era's colonial-style military outposts in the region.
The interior is significantly cramped, reflecting the harsh conditions imposed on political dissidents of the era.
It is situated near the mouth of the Chanthaburi River, chosen strategically for colonial naval control.
The prison was part of a larger French military compound that included a nearby fort, Khai Phai Lom.
Khuk Khi Kai, known as the Chicken Poop Prison, is a historical ruin located in the Laem Sing District of Chanthaburi, Thailand. Constructed by French colonial forces around 1893 during the Paknam Incident, the structure served as a detention center for Thai nationalists who opposed French occupation. The building is a two-story red brick structure measuring approximately 4.4 meters wide and 7 meters high. Its name derives from the reported historical practice of housing chickens on the upper floor, allowing excrement to fall onto prisoners detained in the lower level. The prison walls feature small, slit-like windows intended to facilitate ventilation while maintaining high-security containment. It stands as a physical reminder of the Franco-Siamese War and the territorial disputes of the late 19th century. The site remains a preserved historical monument maintained by local authorities.

Combine your visit with the nearby King Taksin Memorial and the French-era fort at Laem Sing Beach.
The site is small and lacks shade inside, so wear a hat and sunscreen.
Respect the site as a war memorial; keep voices low to maintain the solemn atmosphere.
Do not mistake the nearby ruins of the French fort for the prison itself; both are historic but distinct sites.
Maintain a respectful tone; avoid climbing on the fragile brick walls.
