Abstract
The classification of towers called "Bhawan" of Darbars has distinguished in the previous paper three forms. I discuss the structures of the each forms of towers. As a result, I was able to draw out the following conclusion : The main features comprising the structural system of the Bhawan are an outer quadrille wall and a wall running through the center of the building on the longer axis of the building. This type of structure system is generally employed in the traditional Nepalese architecture including residential houses. I can recognize the historical importance of Bhawan's tower structure in building a higher space for human in Shah Dynasty.
