The Kathmandu Valley is more than an open-air museum of fascinating temples, it is home to a large population that is a diverse mix of cultures and ethnic groups.  Over thousands of years, many people have settled in this area of Nepal after migrating from India to the south and Tibet to the north.
The Valley of Kathmandu is fertile, flat and compact. It is situated at the altitude of between 1,200 to 1,500 meters (between 4,000 to 5,000 feet). The valley is also small, with an area of only 220 square miles (570 square kilometers). Yet in its smallness, there are record seven World Heritage Sites declared by the UNESCO - a fact unrivalled anywhere in the world! The seven man-made wonders are the milestones of Nepal's past and a "living museum".
