[1] In 1930, a well-known wealthy man in British rule, Sir Pho Thar, built and donated a 50-bed station hospital as an ancient colonial style building.

Thus, it was known as Sir Pho Thar Hospital at that time.

It was upgraded to 100-bed general hospital in 1952, 150-bed with specialty units for dentistry, orthopedics, laboratory and radiology in 1965 and 300-bed in 1991.

With all these development, it became a central level government hospital in July 1995.

[1] In 1996, a new 3-storey building and a guard ward for imprisoned patients with 20 beds were developed.
