Munger, formerly spelt as Monghyr,[7] is a twin city and a Municipal Corporation situated in the Indian state of Bihar.

Munger was one of the major cities in Eastern India and undivided Bengal during Mughal period and British Raj.

The twin city comprises Munger and Jamalpur situated on the southern bank of the river Ganges.

Munger is said to have been founded by the Guptas (4th century CE) and contains a fort that houses the tomb of the Muslim saint Shah Mushk Nafā (died 1497).

In 1763, the Nawab of Bengal Mir Qasim made Munger his capital and built an arsenal and several palaces.

[10]: 121  The name is derived from Sanskrit mudga, referring to the mung bean, plus giri, meaning hill.

A copper plate grant of the Gahadavala ruler Govindachandra indicates that he advanced as far as Mudgagiri in April 1146, and bathed in the Ganges here on the day of Akshaya Tritiya.

[12]: 59, 92, 107 Historically, Munger was located at a strategic bottleneck controlling the main route into Bengal from the west.

To the south, travel was impeded by the steep hills; to the north, the numerous Ganges tributaries were the main obstacle.

[citation needed] Munger is known for Sita Manpatthar (Sita charan) Sitacharan temple situated on a boulder in the middle of the Ganges in Munger (Anga Region) is the main center of public faith regarding Chhath festival.

People from all over the city join this yatra, and the deity is immersed early in the morning in the holy river Ganges.

The former is the main railhead for the city while the latter, which was earlier called Purabsarai Railway Station, acts as suburban facility.
