Nakhon Phanom airport was established during the Vietnam War to facilitate the transportation of supplies and troops for the US military. The airport served as a strategic location for the US Army to access Vietnam by flying over Laos which borders Thailand.
In the landscape painting exhibition "The Boundary Of Solitude", the artwork Secret Airport by Vacharanont Sinvaravatn depicts Nakhon Phanom. To create landscape paintings, Vacharanont travelled to the Phu Phan Mountain Range border which passes through four provinces in Isan -- Sakon Nakhon, Kalasin, Mukdahan and Nakhon Phanom.
