In the early 12th century, the Khmer Empire, located in what is today Cambodia, undertook one of the most ambitious architectural projects in the history of Southeast Asia: the construction of Angkor Wat. Originally dedicated to the Hindu god Vishnu, this temple complex reflects the height of Khmer architectural, artistic, and spiritual achievement. Angkor Wat is distinguished not only by its vast scale and ornate design but also by its significance as a symbol of Cambodian national pride and identity. Its transition from a Hindu to a Buddhist temple mirrors the wider religious and cultural shifts in the region over the centuries. Today, Angkor Wat stands as a testament to the ingenuity and devotion of the Khmer people, attracting scholars and tourists from around the globe.
