If you are in Nha Trang, it is well worth a visit. There are many photos in the museum (some of which were taken by Yersin himself), and many scientific devices, tools and letters from Yersin to his mother, which are small snapshots of his research at the time. The museum has been built for years, and is small in the Pasteur Institute. It contains many documents, books and manuscripts about Dr. Jellson. If you are not interested in the medicalist, don't come, or you will feel like a waste of 10 to 15 minutes. The ticket is 20,000 VND per person.
