Gangtok is the capital and largest town of the Indian state of Sikkim. Gangtok is located in the Shivalik Hills of the eastern Himalayan range, at an altitude of 1,437 metres (4,715 ft). The town, with a population of thirty thousand belonging to different ethnicities such as Nepalis, Lepchas and Bhutia, is administered by various departments of the Government of Sikkim. Nestled within higher peaks of the Himalaya and enjoying a year-round mild temperate climate, Gangtok is at the centre of Sikkim’s tourism industry.

Gangtok rose to prominence as a popular Buddhist pilgrimage site after the construction of the Enchey Monastery in 1840. In 1894, the ruling Sikkimese Chogyal, Thutob Namgyal, transferred the capital to Gangtok. In the early 20th century, Gangtok became a major stopover on the trade route between Lhasa in Tibet and cities such as Kolkata (then Calcutta) in British India. After India won its independence from Britain in 1947, Sikkim chose to remain an independent monarchy, with Gangtok as its capital. In 1975, after Indian annexation, Gangtok was made India’s twenty-second state capital.

The precise meaning of the name Gangtok is unclear, though the most popular meaning is “hill top”. Today, Gangtok is a centre of Tibetan Buddhist culture and learning, with the presence of several monasteries, religious educational institutions, and centres for Tibetology. -Wikipedia
