Foundation and Construction
Angkor Wat was constructed during the reign of King Suryavarman II in the early 12th century (approximately 1113-1150 AD). The Khmer Empire, which had its capital at Angkor, was one of Southeast Asia’s most powerful and enduring empires. The decision to build Angkor Wat was both a political and spiritual undertaking, symbolizing Suryavarman II’s divine right to rule and his devotion to the Hindu god Vishnu.

Architectural Design and Symbolism
The temple’s design is a reflection of Hindu cosmology, specifically the concept of Mount Meru, the mythical home of the gods. Angkor Wat’s central tower represents the peak of Mount Meru, while the surrounding smaller towers symbolize the mountain’s lower peaks. The moat and the rectangular outer wall represent the oceans and the edge of the world, respectively.
Constructed primarily from sandstone, the temple showcases the Khmer architectural style, characterized by towering spires, intricate bas-reliefs, and extensive galleries. The site covers approximately 162 hectares, making it the largest religious monument globally.

Architectural and Artistic Marvels
The Central Tower and Galleries
The central tower, the highest point of the temple, symbolizes Mount Meru and is a focal point for both religious ceremonies and the overall architectural design. The galleries surrounding the central tower are adorned with more than 1,200 square meters of bas-reliefs, featuring over 20,000 carved figures. These carvings provide a detailed glimpse into the religious, cultural, and military aspects of the Khmer Empire.
The Gopuras (Entrance Pavilions)
The temple’s entrances are marked by gopuras, or monumental towers, each intricately decorated and aligned with the cardinal points. The western entrance, the main approach to the temple, is particularly significant as it is traditionally the direction associated with death in Hinduism, symbolizing the temple’s dual role as a mausoleum for Suryavarman II.
The Moat and Causeways
The expansive moat, which measures approximately 1.5 kilometers by 1.3 kilometers, serves both a practical and symbolic purpose. It represents the cosmic ocean and provides a protective barrier. The causeways, lined with balustrades shaped like mythical serpents (nagas), lead visitors into the sacred space of the temple, emphasizing the journey from the mundane to the divine.

From the grandeur of Angkor Wat to the enigmatic faces of the Bayon and the jungle-clad ruins of Ta Prohm, these temples offer a profound insight into the religious devotion, artistic mastery, and historical legacy of the Khmer Empire.
