The present work is based on the survey work done which includes detailed physical examination of the different parts of the forts of Rajasthan and Mughal buildings at Fatehpur Sikri, Agra and Delhi. To avoid enlargement and save time and space, we have selected forts of Amber, Udaipur, Chittor, Jodhpur and Bikaner to study the influence of Mughal architecture and Fatehpur Sikri, Agra and Delhi to study the influence of Rajputana architecture.In the present thesis an attempt is made to study the interaction between the two different schools- architecture of Rajputana and architecture of Mughal by corroboration of the findings of survey with the textural references.
