Gurudwara Bibi Bhani da Khuh, situated near Sri Darbar Sahib Tarn Taran, is named after Bibi Bhani Ji. She was the daughter of Guru Amar Das, the wife of Guru Ram Das, and the mother of Guru Arjan Dev Ji. This religio-historic khuh (well) was dug by Guru Arjan Dev Ji in memory of his mother at the place where she used to serve food, water, and medicine to the needy and visiting pilgrims. Locals preserved the place with the help of Dera Kar Sewa Tarn Taran, and constructed a Gurudwara.
