Udon Thani

Udon Thani stands in the northern Khorat Plateau, south of the Mekong and the old settlements around Nong Khai. The place was formerly known as Ban Mak Khaeng. Its surrounding country belongs to the Sakon Nakhon basin, where streams drain toward the Mekong through a landscape of plains and low hills. Across the great river lay Vientiane, a major centre of the Lao kingdoms.
