The Berlin Pharmaceutical Museum, located at the intersection of Si Pha Road, was established in memory of Dr. Chai Chaiyanuwat. Originally, this building was a small clinic run by Dr. Chai, where he treated general patients after graduating in Western medicine from China. His selflessness and willingness to care for patients regardless of their financial situation made him well-known at that time. Inside the museum, the clinic's patient treatment room has been replicated, showcasing medical equipment from the past arranged to reflect the historical setting. This creates a nostalgic atmosphere for visitors to experience. Additionally, there are various interesting rooms, such as the pharmacy corner, where you can see how medications were prepared in the old days—ground, weighed, measured, and combined for each patient, along with the appearance of bottles and labels used for medicines. Another fascinating section is the Memory Room, which presents the history of the Berlin Pharmacy and important historical events, such as World War II. It includes items from the time that illustrate the lifestyle of people back then, such as traditional pillows used for smoking. The museum is open for visits every day, except Mondays, from 9:00 AM to 5:00 PM. The entrance fee is 40 baht per person.
