Siriraj Bimuksthan Museum

Housed in the beautifully restored vintage architecture of the former Bangkok Noi Railway Station, this museum serves as the historical gateway to the hospital grounds. It chronicles the history of the area from the Ayutthaya period to the founding of Siriraj Hospital by King Rama V. Unlike the medical-heavy rooms nearby, this museum focuses on local history, traditional Thai medicine, and the archaeological remains discovered during the station's renovation, including a massive 24-meter ancient wooden boat.

Pathological Museum

The Pathological Museum is a sobering look at the various diseases that affect the human body. It features a vast collection of preserved organs and foetuses affected by congenital anomalies, genetic disorders, and different types of cancers. It is designed to show the physical manifestation of disease—such as the effects of heart disease or stroke—offering a stark, visceral reminder of human vulnerability and the importance of medical pathology in saving lives.

Anatomical Museum

Established in 1948, this museum is a masterclass in the complexity of the human frame. It contains over 2,000 exhibits, ranging from meticulously dissected nervous systems and muscles to entire skeletal remains. One of its most famous displays is a "dissected" nervous system that spans an entire wall, showing the intricate web of nerves throughout the body. It remains a vital study center for medical students learning the foundational "map" of human biology.

Forensic Medicine Museum

This is perhaps the most famous (and intense) part of the cluster. It functions as a repository for evidence from homicides, accidents, and unnatural deaths. For decades, the star exhibit was the mummified remains of See Uey, a notorious serial killer, though his body was finally cremated in 2020. Today, the museum still displays the remains of unidentified victims and evidence of various causes of death—such as gunshot wounds or blunt force trauma—to educate the public on forensic science and the legal process.

Parasitological Museum

This museum focuses on the "hidden" world of organisms that thrive at the expense of human hosts. The exhibits detail the life cycles of protozoa, flatworms, flukes, and insects like mosquitoes and ticks. It is particularly relevant given Thailand’s tropical climate, showcasing preserved specimens of giant intestinal worms and the physical deformities caused by diseases like Elephantiasis (lymphatic filariasis).

Prehistoric Museum and Laboratory

Dedicated to the father of Thai prehistory, Dr. Sood Sangvichien, this museum bridges the gap between medicine and archaeology. It displays prehistoric human skeletons, tools, and pottery found across Thailand, particularly from the Ban Chiang and Kanchanaburi sites. The laboratory aspect highlights how forensic techniques are used to study ancient remains, helping researchers determine the diet, health, and lifestyle of humans who lived thousands of years ago.
