The National Museum is located just outside the city of Chumphon on the way to Thung Wua Laen on a fenced-in area shared with the provincial organization.
It is a two-story building. The library and service facilities are on the 1st floor. The 2nd floor houses the actual exhibition rooms.
In addition to artifacts from the area's millennia-old settlement history, photographs and model buildings, the exhibition also includes a multimedia presentation of the events during the destructive Typhoon Gay, which hit the province of Chumphon in November 1989. The Japanese attack on Thailand during the Second World War (1942), which originated in Chumphon, is also reported in detail.

In an exhibition room on the 2nd floor, paintings by the Thai King Bhumibol Adulyadej (Rama IX) are on display, which, in addition to a nude, mainly depict portraits of Queen Sirikit.

Definitely worth a visit. Entrance fee 100 THB. It gives you an insight into the history of Thailand and life in the past. I can only recommend that you take a look at it as a European.
