Gurdwara eat free vegetarian food brought in by Sikhs worshiping at the "gurdwara". They may also have a library, nursery, classroom, meeting rooms, a gift shop, and finally a repair shop. A "gurdwara" can be identified from a distance by tall flagpoles bearing the "Nishan Sahib", the Sikh flag. The most well-known "gurdwara" is the Harmandir Sahib (popularly known as The Golden Temple) in Amritsar, Punjab, India, which is the center of power (Akal Takht) of Sikhism. The first "gurdwara" was built in Kartarpur, on the banks of Ravi River in the Punjab region by the first Sikh guru, Guru Nanak
Dal Khalsa (International) the followers of a Sikh sect known as the Nirankaris (whom other Sikhs regard as heretics). This clash had occurred at a Nirankari event at the Harmandir Sahib in Amritsar on 13 April 1978, in which 3 Nirankaris and 13 Sikhs were killed. At its first annual conference held in Gurdaspur during December, 1979, the Dal Khalsa passed a resolution demanding that Amritsar be officially declared a "holy city". A demand that was supported by other Sikh organisations such as the Sikh Students Federation and one which was later taken up with the Indian government by the SGPC in 1980.
