The Upper Himmalayahs. View in the Buspa Valley from Sangla

The 50 images in this album, all taken in the 1860s, move from the hill towns of the Himalayas down to cities including Lahore (now in Pakistan), Delhi, Lucknow, Agra, Benares (now Varansi), and Calcutta (now Kolkata). Architectural studies of major monuments offer valuable historical records of what sites such as the Taj Mahal and the imperial mosque of the Mughal emperors in Delhi looked like before 20th-century restorations.
