Wat Rong Khun
Temple of Heaven
Chion-in Temple [wiki] was built in 1234 CE to honor the founder of Jodo (Pure Land) Buddhism, a priest named Honen, who fasted to death in the very spot. At one point in time, the complex had 21 buildings but due to earthquakes and fire, the oldest surviving building is from the 17th century.
In the 19th century, Dutch occupiers of Indonesia found a massive ancient ruin deep in the jungles of Java. What they discovered was the complex of Borobudur, a gigantic structure built with nearly 2 million cubic feet (55,000 m³) of stones. The temple has nearly 2,700 relief panels and 504 Buddha statues.
The Harmandir Sahib (meaning The Abode of God) or simply the Golden Temple [wiki] in Punjab, India is the most sacred shrine of Sikhism. For the Sikhs, the Golden Temple symbolizes infinite freedom and spiritual independence.
Vishnu Temple of Srirangam
The Temple of Srirangam (Sri Ranganathaswamy Temple [wiki]), in the Indian city of Tiruchirapalli (or Trichy), is the largest functioning Hindu temple in the world (Ankor Wat is the largest of all temple, but it is currently non-functioning as a temple).
The temple complex is massive: it encompasses an area of over 150 acres (63 hectares) with seven concentric walls, the outermost being about 2.5 miles (4 kilometers) long! The walls demarcate enclosures within enclosures, each more sacred than the next, with the inner-most enclosure is forbidden to non-Hindus.
Angkor Wat, Angkor Thom, and Bayon
Last but definitely not least is the largest temple in history and the inspiration to countless novels and action movies of Hollywood: Ankor Wat.
The Western world’s got a glimpse of Angkor Wat when a 16th century Portuguese monk visited the temple and eloquently described it as "of such extraordinary construction that it is not possible to describe it with a pen, particularly since it is like no other building in the world. It has towers and decoration and all the refinements which the human genius can conceive of." His words still rang true today.
