Morphology is the science of form and structure and development which influence the form of the city. It deals development of forms and pattern of the present city. In this paper an attempt has been made to discuss the morphology of Munger city it is also known as ‘YOGA NAGARI’. Munger is a historical city situated between the broad Ganaga washing it on two sides and the ancient hill of Dharwarian period in the background. Thus the morphology of Munger city is highly influenced by the river Ganga and the adjoining low lying and hilly areas. It lies in the loop of the Ganga which incircles it from the West and north. The rectangular fortifying wall is situated at the point of turn in the river. Hence the city has expanded eastward and southward from the fort and in the and absence of any low lying area or hill restricting its growth it is likely to maintain its rectangular shape. The internal shape ofthe city has been changed after highly destructive earthquake on 15 January 1934.
