The power of nature! 1400 Years ago, the Romans built a massive wall around the port city of Ashkelon. The Sahara sand, Mediterranean currents and winds constantly "biting" the wall and slowly but surly, covered it to the extent we can climb the walls with our 4x4's... Ironically, the cutting edge of architecture today, striving towards "sustainable structures", is displayed in front of us by the 1500 year old Roman structure, naturally decaying... Ashkelon Roman wall. Location: Southern Ashkelon.
