Nepal (i/nɛˈpɔːl/ne-PAWLNepali: नेपाल[neˈpal] ( listen)), officially the Federal Democratic Republic of Nepal, is a landlockedsovereign state located in South Asia. With an area of 147,181 square kilometres (56,827 sq mi) and a population of approximately 27 million (and nearly 2 million absentee workers living abroad), Nepal is the world's 93rd largest country by land mass and the 41st most populous country. It is located in the Himalayas and bordered to the north by the People's Republic of China, and to the south, east, and west by the Republic of India. Specifically, the Indian states of Uttarakhand, Uttar Pradesh, Bihar, West Bengal, and Sikkim border Nepal, while across the Himalayas lies the Tibetan Autonomous Region. Kathmandu is the nation's capital and largest metropolis.
The Kathmandu Valley (Nepal Bhasa: स्वनिगःSvanigaḥ[sʷoniɡəː], Nepali: काठमाडौँ उपत्यका), located in Nepal, lies at the crossroads of ancient civilizations of Asia, and has at least 130 important monuments, including several places of pilgrimage for the Hindus and the Buddhists. There are seven UNESCO World Heritage Sites within this valley. Historically, only the Kathmandu Valley was referred to as "Nepal" by people who lived outside the valley. After the annexation of the valley by the Gorkha kingdom, and subsequent conversion of the valley as the capital of their empire, this designation of "Nepal" was extended to every land they conquered. The valley itself was referred to as "Nepal Proper" by British historians.
