Gurdwara Darbar Sahib, also known as Kartarpur Sahib, is one of the holiest Sikh pilgrimage sites, located in Kartarpur, Narowal District, Punjab, Pakistan. It marks the place where Guru Nanak Dev Ji, the founder of Sikhism, spent the last 18 years of his life and passed away in 1539. Established by Guru Nanak, this gurdwara is revered for its spiritual significance and its role in fostering unity, particularly through the Kartarpur Corridor, opened in 2019, which allows visa-free access for Indian pilgrims. The serene complex, with its white marble architecture and tranquil sarovar (sacred pond), attracts thousands of devotees and tourists seeking spiritual connection and historical insight.
