Amritsir, Or Umritsir, a town of the Punjaub, Hindostan, between the Ravee and the Bens, an affluent of the Sutlej, 36 m. E. of Lahore; pop. about 130,000. There is in the town an extensive tank, built, or rather restored, in 1581, by Ram Das, the 4th Guru or holy man of the Sikhs, the name of which - Amritsir, the pool of immortality - was in the course of time transferred to the whole town. In the centre of the pool is a temple sacred to Govind Singh, the last of the Gurus. Amritsir is a place of considerable trade, one of the commercial depots of N. W. India. It is an open town, but Runjeet Singh built a fort there in 1809.
