Rome is so filled with treasures that it is often hard to know where to start. Sometimes it is easier to concentrate on one artist like Caravaggio or architect such as Bernini (who is almost impossible to avoid anyway). The last time we were in the city we decided to give one day to a Roman emperor, Hadrian, who ruled from AD 117 until his death in AD 138.

One of the few emperors who still gets good press as an administrator, he was a great traveler and builder, particularly in Rome.
