Thakhek
Thakhek is a former trading port in central Laos. It's on the Mekong River, bordering Thailand. The old town has French colonial buildings from the early 20th century. South of the center, the centuries-old, golden-tipped Sikhottabong Stupa is believed to house Buddhist relics. The massive Kampaeng Yark sandstone wall north of town might once have been a defensive structure.
