This is from our vacation in the "eternal" city of Rome and of course one place to visit is Colosseum. It is had some issues with time, but if you stop and think what is has been about 2000 years ago you can't stop been amazed by it.
That is one amazing thing too how they did that, and even how they did bring water to Rome. And concrete they used 2000 years ago was more sustainable than we use today.
Ich möchte gerne mal Urlaub machen in Rom. ;)
One has give a fair recognition to Roman engineering, this is one fine example of how good it was at that time.
In ancient Rome they even used to flood it and have naval battles there.
