Some cool stuff. Of course I couldn't help but notice this little error:
The Roman coliseum at El Djem, Tunisia in northern Africa was built nearly
1,700 centuries ago, which may account for why the surrounding sites are mostly covered in sand. This coliseum is often referred to as an amphitheatre. Regardless what you call it, it is one of the most impressive of its kind and in better condition than its more famous counterpart in Rome.
1700 centuries!

Who knew the Romans were around and building elaborate structures 170,000 years ago?
