Nainital is a popular hill station in the Indian state of Uttarakhand and headquarters of Nainital district in the Kumaon foothills of the outer Himalayas. Situated at an altitude of 2,084 metres (6,837 ft) above sea level, Nainital is set in a valley containing an eye-shaped lake, approximately two miles in circumference, and surrounded by mountains, of which the highest is Naina (2,615 m (8,579 ft)) on the north, Deopatha (2,438 m (7,999 ft)) on the west, and Ayarpatha (2,278 m (7,474 ft)) on the south. From the tops of the higher peaks, "magnificent views can be obtained of the vast plain to the south, or of the mass of tangled ridges lying north, bound by the great snowy range which forms the central axis of the Himalayas."

The Kumaon Hills came under British rule after the Anglo-Nepalese War (1814–16). The hill station town of Naini Tal was founded only in 1841, with the construction of the first European house (Pilgrim Lodge) by P. Barron, a sugar trader from Shahjahanpur. In his memoir, he wrote: "It is by far the best site I have witnessed in the course of a 1,500 miles (2,400 km) trek in the Himalayas." In 1846, when a Captain Madden of the Bengal Artillery visited Naini Tal, he recorded that "houses were rapidly springing up in most parts of the settlement: some towards the crest of the military ranges were nearly 7,500 ft (2,300 m) above sea level: the rugged and woody Anyarpatta Aashish (Anyar-patt – in Kumaoni means – complete blackout. The reason for this nomenclature by the locals was because there were minimal sun rays due to its location and dense forests) was being gradually planted and that the favourite sites were on the undulating tract of forest land which stretched back from the head of the lake to the base of China and Deopatta (Camel's Hump). The church, St. John(1846) in the Wilderness, was one of the earliest buildings in Nainital, followed by Belvedere, Alma lodge, Ashdale Cottage(1860)..." Soon, the town became a health resort favoured by British soldiers and by colonial officials and their families trying to escape the heat of the plains. Later, the town became the summer residence of the governor of the United Provinces.
