Abstract
This paper is one of the reseach in Chok (quadrangle) Architecture of the Royal Buildings of Nepal. In this paper, I examined a history of existing typical Chok Architecture on the basis of records including chronicles and inscriptions, determined to what age that form of buildings could be traced back, and dealt with the functions of them. Findings are as follows : Founding of Mul Chok dates back to the Malla Dynasty at the Royal Buildings of Bhadgaon in the 14th century. It was in the middle of the 17th century when Sundara Chok was constructed as form with a watering place at the Royal Buildings of Kathmandu as well as Patan. In the Shah Dynasty, Vasantapur Chok which had lasted since the Malla Dynasty was augmented to build a new form of architecture. Each Chok Architecture have his own function. Mul Chok is a place of Taleju cult and religious vituals, Sundara Chok and Mohan Chok are places of life, and Mani Kesav Narayan Chok and Vasantapur Chok are places of administration. Characteristics of Chok Architecture during these changes and functions are illustrated by side-by-side standing of Chok with religious functions and one with life functions and, as times changes, by differentiation of functions and addition of new forms of Chok. It can be judged that the Royal Buildings have come up to the present form as a complex which has anaggregate of these Chok Architecture as main componentes.
