File:Central Jail gate, Junagadh.jpg

English: Photograph of the main entrance to the Central Jail at Junagadh in Gujarat, taken by F. Nelson in the 1890s. The album is inscribed: “With best compliments from H.H. Rasulkhanji, Nawab of Junagadh (India)” and was formerly in the collection of Sir William Lee-Warner (1846-1912), who served in the Indian Civil Service and was a Member of the Council of India between 1902 and 1912. This is a view of the jail entrance set in a high wall, with sentries standing outside and on the roof. The design of the jail within is a version of the panopticon system proposed for prisons in 1791 by the English philosopher Jeremy Bentham. Cells are arranged in concentric rings around a watchtower from which prisoners could be observed. In late 19th-century India this was considered a modern form of construction and was used for new prisons in Gujarat and other states.
