The Kathmandu Valley (Nepal Bhasa: स्वनिगः Svanigaḥ [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.
