Today on the Coolest Places on Earth: We're on the road to ruins...ancient ruins that is. Breathtaking, mysterious, and in every way awesome. From the Great Pyramid of Giza to the Great Wall of China, and from grand temples to dramatic dwellings. We're on a mission to find what's still standing, and discover the wonders of centuries past. So hold on to your passports; we're globetrotting.
