Three Great Roman Institutional Innovations are as follows:

• Roman Law:This innovation was indeed an institutional advance. Roman jurists built an elaborate legal system.
• Science and Technology:The Romans, always practical, made few theoretical innovations but applied across their empire advances in public health and hygiene.
• Architecture and Sculpture:The Romans advanced arches to the barrel vault, a series of arches that could provide a ceiling for huge public buildings.

Rome, while not a cultural desert, did not innovate in art, drama, or philosophy.
