Borubadour in Indonesia...Should be a natural wonder. Constructed from every angle to be a work of art, and not one ounce of mortar to connect the thousands upon thousands of individually carved pieces. It's constructors and intended purpose unknown.
Angkor Wat, Siem Reap, Cambodia.Spanning roughly 250 miles, Angkor Wat is the world’s largest religious monument. It’s also a powerful throwback to the Khmer Empire, the Hindu-cum-Buddhist government of Southeast Asia that ruled between AD 802 and 1431. In fact, the entire structure of the wat—or temple—mirrors the Hindu cosmos. Today, it attracts scores of visitors yearly for its impressive infrastructure and spiritual atmosphere.
