From SPUR:

Ancient Rome was very much an urban culture whose city planning traditions evolved through direct contact with the Greeks and Etruscans. Urban designer Eva Liebermann will show how the Romans adapted previous planning practices for their own purposes and created thriving cities with the use of new materials (particularly concrete); the introduction of new building techniques; the development of innovative architectural forms and assemblages such as market places, administration and court buildings, arenas, amphitheaters, temple precincts, baths and engineering marvels as evident in their road system, bridges and aqueducts.
