Photograph of the Golden Temple at Amritsar by an unknown photographer in the 1860s, from the Crofton Collection: 'Topographical and architectural views mostly in India'.

The Hari Mandir or Golden Temple at Amritsar stands in the middle of a tank known since the time of the fourth Guru Ram Das (1574-81) as the Amrit Sarovar or ‘Pool of Immortality-Giving Nectar’. Sikh devotees regard the temple as an important pilgrimage site and come to bathe in the purifying waters of the tank, view the temple deity and receive religious teachings from the original Sikh holy book, the Adi Granth.

The clock tower seen behind to the right of the golden sanctum and pool was built in the 1860s by the colonial British India after the Second Anglo-Sikh War and annexation of the Sikh Empire, despite opposition by the Sikh community. The Gothic Cathedral-style tower was completed in 1872. It was demolished about 70 years later.
