• Guru Nanak Dev, the first Sikh Guru had arrived in Kartarpur between 1520 and 1522, as per historians, and spent the last 18 years of his life there. It was in Kararpur that he laid the foundations of a Sikh religion. At his final resting place stands the gurdwara.
• The Kartarpur was finally thrown open in 2019 with the two sides agreeing on visa-free travel for Indian pilgrims to the shrine. The corridor was shut in March this year in view of the coronavirus pandemic.
