Gurdwara Darbar Sahib Kartarpur, also called Kartarpur Sahib, is a gurdwara in Kartarpur, located in Shakargarh, Narowal District, in the Punjab province of Pakistan. It is built on the historic site where the founder of Sikhism, Guru Nanak, settled and assembled the Sikh community after his missionary travels (udasis to Haridwar, Mecca-Medina, Lanka, Baghdad, Kashmir and Nepal) and lived for 18 years until his death in 1539. It is one of the holiest sites in Sikhism, alongside the Golden Temple in Amritsar and Gurdwara Janam Asthan in Nankana Sahib.
The gurdwara is also notable for its location near the border between Pakistan and India. The shrine is visible from the Indian side of the border. Indian Sikhs gather in large numbers on bluffs to perform darshan, or sacred viewing of the site, from the Indian side of the border. The Kartarpur Corridor was opened by Pakistani Prime Minister Imran Khan on 9 November 2019, the anniversary of the fall of the Berlin Wall and just days before the 550th birth anniversary of Guru Nanak. This historic moment officially allowed Indian Sikh pilgrims rare visa-free access to the site in Pakistan. It is also claimed to be the largest gurdwara in the world. For the first ever commemoration of Baba Nanak's death anniversary, please see Baba Nanak’s joti jot samaunh purab at Kartarpur.
The importance of the Kartarpur corridor is immense for Sikhs, both in India and Pakistan. Governments of both the countries have been jointly working to help Indian Sikhs enter the other side of the border into Pakistan to visit Gurdwara Darbar Sahib in Punjab, Pakistan. The Kartarpur corridor serves as a bridge between the two holy shrines, one, the Dera Baba Nanak Sahib in Punjab, India, and the other is the Gurdwara Darbar Sahib in Punjab, Pakistan.
It is believed that Kartarpur was founded by Guru Nanak himself, the first Guru in Sikhism. After the partition of India, Kartarpur was geographically placed in the Pakistan side, while India got Gurdaspur on the left bank of the River Ravi.
