On our way to Phonsavan.
A neglected archeolocial site is Hintang. Most infrastracture is detoriating.
Too far to go there. Some nice hikes to the several 100 menhires would be possible. We just were able to visit the main site.

The discs once covered burial holes some meters deep with several urns.

At lest 1500 years old but not much is known. The entire site is spread over 10 km.
