WOW - I've always wanted to go there to see the ruins. Amazing stuff!
I had no idea those civilizations were as advanced as they were.
Ephesus had running water and a sewage system.
The sewage system in Pompeii was awful. According to our guide they actually allowed raw sewage to flow down the street. There were raised stones in the street on which to step in order to cross the street without stepping in sewage.
I feel so priviledged to have been able to see these ancient ruins.
