The Great Wall of China is decaying and overgrown with vegetation can be seen atop a small hill near Xiang Shui Hu village, located 80 km (50 miles) northwest of Beijing September 30, 2012. Voted one of the New Seven Wonders of the World, the 6,400 km (4,000 miles) wall snakes its way across 11 Chinese provinces and draws millions of tourists every year, mostly to restored sections near the capital, Beijing. But away from the tourist trail, some parts of the wall are being allowed to crumble away. - Photos by Reuters
