Pyu city-states
Beikthano ( ) situated in the irrigated Minbu region (near present-day Taungdwingyi) with direct land access to the well-watered Kyaukse plains to its northeast, is the oldest urban site so far discovered and scientifically excavated site. Its remains—the structures, pottery, artefacts, and human skeletons—date from 200 BCE to 100 CE. Named after the Hindu god Vishnu, the city may be the first capital of a culturally and perhaps even politically uniform state in the history of Burma. It was a large fortified settlement, measuring approximately 300 hectares inside the rectangular (3 km by 1 km) walls. The walls and fortifications along it measured six meters thick, and are radiocarbon dated to a period between 180 BCE and 610 CE. Like most subsequent cities, the main entrance of the walls led to the palace, which faced east. Stupas and monastic buildings have also been excavated within the city walls.
History of Myanmar
The earliest archaeological evidence suggests that cultures existed in Burma as early as 11,000 BCE. Most indications of early settlement have been found in the central dry zone, where scattered sites appear in close proximity to the Irrawaddy River. The "Anyathian", Burma's Stone Age, existed at a time thought to parallel the lower and middle Paleolithic in Europe. The Neolithic or New Stone Age, when plants and animals were first domesticated and polished stone tools appeared, is evidenced in Burma by three caves located near Taunggyi at the edge of the Shan plateau that are dated to 10000 to 6000 BC.
