more: Over 400 prehistoric sites have been excavated in Burnt City and archeologists expect the number to reach 1000.

The 5000-year-old Burnt City is located near the city of Zabol and covers an area of over 300,000 hectares.

Four civilizations have lived in the city which was burnt down three times; it was not rebuilt after the last fire.

The world's oldest animated picture-book, dice and backgammon set, the earliest known caraway seed and artificial eyeball all been found in the Burnt City.

Archeology is so fascinating. Imagine finding things that were made by people not just a few hundred tears in the past but thousands, and finding civilizations on top of civilizations.

It makes me sick to think of the historical treasures
and knowledge have been lost to wars.
