Jammu district derives its name from the city of Jammu which besides being the winter capital of the state, is known as the city of temples. It is believed that the city was originally founded by Raja Jamboo Lochan who lived in fourteenth century B.C. The Raja had gone out one day for hunting when he happened to witness a tiger and a goat drinking water from one and the same pond. This extraordinary phenomenon set him thinking and he decided to build a city at this site so that the strong and weak could live together in peace and mutual tolerance. Eventually, he founded the city which came to be known as "Jamboo" after his own name. With the passage of time and due to its frequent use the pronunciation of the name got slightly distorted and the city, came to be known as 'Jammu' as it is called now
Jammu is situated on a hillock, on the bank of river Tawi and is bound by Udhampur district in the north and northeast , Kathua district in the east and southeast, Pakistan (Sialkote) in west and Rajauri district and POK (Bhimber) in the northwest. Its skyline was once dotted with glittering spires of temples. These spikes are no longer visible as most of these are hidden behind multi storyed buildings. The city has numerous shrines for Muslims, Sikhs & Christians also. Jammu also serves as base camp for the holy shrine of Vaishno Devi. Jammu is also the Railhead of the state.
