Kathmandu is the capital and largest urban agglomerate of Nepal. The agglomerate consists of Kathmandu Metropolitan City at its core, and its sister cities Patan, Kirtipur, Thimi, and Bhaktapur. It also includes the recently recognized urban areas of Shankhapur, Karyabinayak, and Champapur.Banepa, Dhulikhel, and Panauti are satellite urban areas of Kathmandu located just outside the Kathmandu valley.
The city stands at an elevation of approximately 1,400 metres (4,600 ft) in the bowl-shaped Kathmandu Valley of central Nepal. It is surrounded by four major mountains: Shivapuri, Phulchoki, Nagarjun, and Chandragiri. Kathmandu Valley is part of three districts (Kathmandu, Lalitpur, and Bhaktapur), has the highest population density in the country, and is home to about a twelfth of Nepal's population.
Kathmandu is the gateway to tourism in Nepal. It is also the nerve center of the country's economy.
The city has a rich history, spanning nearly 2000 years, as inferred from inscriptions found in the valley. Religious and cultural festivities form a major part of the lives of people residing in Kathmandu. Most of Kathmandu's people follow Hinduism and many others follow Buddhism. There are people of other religious beliefs as well, giving Kathmandu a cosmopolitan culture. Nepali is the most commonly spoken language in the city. Nepal Bhasa is the indigenous language spoken by the Newar people. Hindi is widely understood and English is understood by Kathmandu's educated residents.
