This broad treatment of architecture throughout the region of the Himalaya mountains is the first book of its kind. The author has based this study on many years of research in Nepal, Sikkim, Bhutan, Assam, and the Darjeeling area of northeast India, northern Pakistan, and Himachal Pradesh in India's northwest. These areas make up an artistic and, to some degree, a cultural unit. It is unique and definable for its design qualities as well as its use of materials.

Dramatic and lofty structures rise as towering palaces and as temples dedicated to Hindu and Buddhist ideals. The impact of neighboring Tibet and India is often evident in the art, but other influences are found as well. The area has not been isolated, as some studies suggest, but was in fact always linked to the rest of Asia and to the West by means of the Silk Road, at least since the second century B.C.

This study progresses from east to west, beginning in the foothills of India's Assam. It is richly illustrated with photographs, most of which are the author's or his wife's, and many of the photographs are published here for the first time. The archives of the Archaeological Survey of India and the Department of Archaeology of His Majesty's Government of Nepal are also used here.
