Nepal, March 31 -- Along with the Sherpa community, it is perhaps Kathmandu Valley's Newah Civilization that has been the most studied by anthropologists, architects, historians and social scientists.

Tomes have been written about the built environment of the Valley's former kingdoms, the influence of Indian culture, and how it in turn inspired the temples, monasteries and monuments in Tibet, through China right up to Korea and Japan.

Lately, there has also been an attempt to recognise and preserve not just the brick and mortar landscape of Kathmandu, but also the intangible heritage of the Newah people. A critical component of the ancient festivals in the streets, alleys and baha of the inner cities are ritual plays and dance.
