Rome In Spectacular Cross-Section by Andrew Solway illustrated by Stephen Biesty*

Intricate drawings display various buildings and structures in Rome during A.D. 128.
The reader follows Titus and his father Marcus around Rome and enter the Temple of Jupiter, the Forum, the Colosseum, the Baths of Trajan, the Circus Maximus and Titus' house. 
Tons of facts and many interesting details to be found in the illustrations.
I read bits of this book to my boys over a few days to support our study of Ancient Rome.
*Highly recommend.
