The clock tower donated by the Vietnamese community to the people of Nakhon Phanom
The clock tower, in the 'walking street' area of town near the river, was built in 1960 by the Vietnamese community, when many of them returned to their fatherland to fight in the 'American' war. Nakhon Phanom is the closest part of Thailand to Vietnam, which is less than 200 kilometers away, across Laos, and the province saw some action during the war. The Americans had a base here and it was thought that many of the province's districts were infiltrated by the Viet fighters.
The tower itself is not very remarkable, but the area around it can be somewhat lively at night.
