The splendidly evocative ruins of ancient Rome have long been a challenge to historians and archaeologists in reconstructing how it looked and functioned. It became the largest city in the western world during the imperial period, so how was the city constructed, and what were the materials used? How was it defended, supplied with food and water, and how were the people housed and entertained, and above all, how did it function? These video tracks use various famous sites such as the Baths of Caracalla and the Pantheon to answer some of these questions. This material forms part of the course AT308 Cities and technology: from Babylon to Singapore.
