Kathmandu is about 1400 meters (4500 feet) above sea level is in a large valley surrounded by four major mountains: Shivapuri, Phulchoki, Nagarjun, and Chandragiri.
Here are some very interesting facts.
People in Kathmandu, and indeed the whole of the country do not greet each other with a handshake. They touch their palms and bow saying 'Namaste' which is translated to mean 'I salute the God in you.’
The shape of their flag is the most unique in the world! I bet it is Quadrilateral. Well, not the National flag of Nepal. It is said to be the most mathematical flag...Frankly, I can't tell what the shape is - just Google it. The Flag has two triangles. One triangle has the sun embedded on it and the other has the moon embedded. The two triangles represent the Himalayan Mountains and two major of the major religions followed here - Hinduism and Buddhism.
The People of Nepal have never been ruled by foreigners...how about that?
Beware! Touching anything with your feet in Nepal and Kathmandu in particular is considered offensive.
Nepal is a country of records. It has the highest mountain in the world, the highest lake in the world, the highest concentration of world heritage sites in the world and many more.
