The Plain of Jars (Lao: ທົ່ງໄຫຫິນ [tʰōŋ hǎj hǐn]) is a megalithic archaeological landscape in Laos. It consists of thousands of stone jars scattered around the upland valleys and the lower foothills of the central plain of the Xiangkhoang Plateau. The jars are arranged in clusters ranging in number from one to several hundred.
