Great blocks of flats or tenements were called insulae. Exca- vations at Ostia, Italy, have revealed the design of these blocks. Planned on three or four floors with strict regard to economy of space, they depended on light from the exterior as well as from a central court. The villa was an estate, complete with house, grounds, and subsidiary buildings. Hadrian's Villa at Tivoli, began about AD 123, was a sumptuous residence with parks and gardens on a large scale.
