Pataliputra is the ancient name of Patna, the present day capital of Bihar.
The Ganduk River empties into the Ganga from the north at Pataliputra, and the Sone enters the Ganga from the south, some miles to the west of the city.
Pataliputra's recorded history began with Ajatshatru, the second of the Magadhan kings, who established a small fort in 490 BCE at Pataligram where the Ganga and Sone Rivers met in order to better fight his enemies, the Licchavis.
Chandragupta's capital was Pataliputra (today, Putra), a city nine by two miles, surrounded by walls of timber, 570 towers, a moat 900 feet wide and 30 feet deep.
An ambassador, Megasthenes, sent to Pataliputra by the Seleucus, described the people of Pataliputra as skilled in the arts, as having an abundance of nourishing food, a low incidence of thievery and people often leaving their houses and property unguarded.
Megasthenes described the people of Pataliputra as uncomplicated in their manners, never drinking wine except at sacrifices, and as seldom going to court against one another.
