In Global context, Mahasthan and its environs is a potential heritage site which is important to understand the cultural development by the ancient civilizations in Bengal as it represents the earliest city state in Bengal. Like many other heritage sites in Bangladesh, Mahasthan faces different challenges due to lack of long term management plan to maintain sustainable development. The Book explores underlying issues of heritage management & planning for the huge site and outlines a comprehensive approach for conservation to foster sustainable development in a critical context where cultural heritage still remains as an isolated issue for main stream development. Like Bangladesh many other developing countries may faces similar challenges to manage their cultural heritage and to promote them in Global context. This publication may be successful if it becomes useful in such case.
