Patna or ancient Pataliputra became Magadha’s capital after the Kings realised the importance of Ganges as a mode of transportation. Rajgir, the initial capital was closer to the mines that were located down south. However, with the rise of Pataliputra, it faded away. When modern Bihar was formed, Patna was a natural choice to be the capital. Theses pictures are from my one day roaming around in Patna.
