Anandpur Sahib is a city and a municipal council in Rupnagar district in the state of Punjab, India. Known as "the holy City of Bliss," it is a holy city of the Sikhs and is one of their most important sacred places, closely linked with their religious traditions and history. It is located on the lower spurs of the Himalayas surrounded by picturesque natural scenery, with the river Sutlej forming a shimmering and shiny blue border on the south west barely four miles away.

Anandpur Sahib comes to life every year on the occasion of Hola Mohalla. This tradition dates back to the times of the 10th Guru, Sri Guru Gobind Singh . The Guru decreed that the occasion of the festival of Holi be the occasion for the display of the martial spirit of his people and he gave this festival of Holi the Sikh name of 'Hola Mohalla'. Each year Hola Mohalla marks the congregation of up to 100,000 devotees from all over the country for a festival of colour and gaiety.

Anandpur Sahib has several Gurudwaras.
Kesgarh Sahib is the name given to the fort that the tenth Master constructed in Anandpur Sahib. The fort is now the Takhat called Keshgarh Sahib. This Gurdwara was one of the five forts constructed by Guru Gobind Singh at Anandpur Sahib for the defense of the Sikhs. It has a number of weapons on holy display.

Gurudwara Sheesh-Ganj Sahib: In November of 1675, the head of the martyred 9th Guru which was brought by Bhai Jaita ( Rechristened Bhai wan Singh according to Sikh rites) in defiance of the Mughal authorities was cremated here.
