Drawing on insights from contemporary urban theory, this contribution questions where medieval urbanization took place. It is proposed that urbanization is a process which extends beyond towns and cities, which are merely a representation of a more expansive and transformative process. Through discussion of building stone, grain production, salt extraction, woodland management and mineral exploitation, it is argued that medieval urbanization was generative of political ecological relations which challenge prevailing understandings of the rural/urban divide and re-frame urbanization as a metabolic process. The discussion utilizes contemporary concepts of ‘extended urbanization’, ‘urban metabolism’ and ‘political ecology’ to re-frame perceptions of medieval–urban relations and the notion of urban hinterland.
