The National Mission for Manuscripts was established in February 2003 by the Ministry of Culture. Its purpose is to locate, document, preserve and disseminate the knowledge content of Indian manuscripts. While looking ahead to reconnect with the knowledge of the past, the Mission is in the process of trying to re-contextualize the knowledge contained in manuscripts for the present and the future generations. The mission organizes seminars on various subjects related to Indian knowledge in different locations of India. The papers presented in the seminar are collected and brought under the Samiksika series. The seminar related to Architecture was organized at ORI&MSS Library, University of Kerala. Dr K. G.
