The crowds, the heat, the Italian trees the ruins in the background
that we simply did not have time to 
explore
I can't even find these ruins in my book on Rome

"Creepy Italian trees!"
Quote from Under the Tuscan Sun

 

Entrance way into 'Old Rome'

 

Reverse of the Arch of Constantine

 

The Arch of Constantine
315 A.D
To commemorate the Emperor's victory over Maxentius 
at the Battle of Milvian Bridge

 

Part of the city's aqua duct system

 

Picture taken from the bus as we drove by...
The pyramid of Caius Cestius (wealthy figure from the Augustan Age)
is 36 meters high and has a base of 30 meters on each side.
It was built in only 300 days

...On our way to the Colosseum

 

                       One of the many Egyptian obelisks that Rome took for their viewing pleasure

                                  See the long line in the back ground? All waiting for the museum
