This multi-disciplinary account of the fate of ancient monuments and technologies in Asia Minor studies the processes and their results with the help of archaeology, history, construction engineering, and travel documentation. To clarify changes, their causes and repercussions, it compares infrastructure engineering (transportation, water management, utilitarian architecture) in antiquity with developments over the past 200 years, using the accounts of European travellers and then of excavations. It analyses patterns of and reasons for the deterioration of material life, documenting the perceptions and understanding of Roman antiquities and engineering by populations living amidst ancient Roman art and architecture, roads, and aqueducts. These are complemented by travellers' accounts of the myriad aspects of the plundering of archaeological sites and antiquities.
