The Kathmandu Valley (Nepali: काठमाडौं उपत्यका, Nepal Bhasa: स्वनिगः, नेपाः गाः), historically known as Nepal Valley or Nepa Valley, lies at the crossroads of ancient civilizations of the Indian subcontinent and the broader Asian continent, and has at least 130 important monuments, including several pilgrimage sites for Hindus and Buddhists. There are seven World Heritage Sites within the valley. Historically, the valley and adjoining areas made up a confederation known as the Nepal Mandala. Until the 15th century, Bhaktapur was its capital, when two other capitals, Kathmandu and Lalitpur (Patan), were established.

In 2015, Kathmandu Valley was hit by the April 2015 Nepal earthquake. The earthquake caused thousands of deaths and destruction of many infrastructures across the Kathmandu Valley, which includes the towns of Lalitpur, Kirtipur, Madhyapur Thimi, Bhaktapur making the total population to roughly five million people and the municipalities across Kathmandu valley. Kathmandu is also the largest metropolis in the Himalayan hill region.
