Most visitors arrive knowing
Angkor Wat is "a temple in Cambodia." What they discover is considerably more. Angkor Wat is the centrepiece of the Angkor Archaeological Park, a UNESCO World Heritage site covering over 400 square kilometres of jungle, ancient waterways, and the ruins of dozens of temples built between the 9th and 15th centuries by the Khmer Empire.
The main temple, constructed in the first half of the 12th century under King Suryavarman II, was originally dedicated to the Hindu god Vishnu. Its architecture is a physical representation of Hindu cosmology: the five central towers represent Mount Meru, the home of the gods; the surrounding moat represents the cosmic ocean; and the concentric galleries depict the layers of the universe. Every carving, every measurement, every alignment was intentional. The temple is oriented to the west, unusually for a Hindu shrine, which some scholars believe was connected to its function as a royal mausoleum. Over 1,700 metres of bas-relief carvings line the inner galleries, depicting scenes from Hindu mythology and Khmer history with extraordinary detail and artistry. The Churning of the Ocean of Milk, a 49-metre panel showing gods and demons pulling a giant serpent to churn the sea into the elixir of immortality, is considered one of the greatest works of art in Southeast Asian history. You could spend an entire morning just on this one gallery.
