Angkor Wat is often hailed as one of the most extraordinary architectural creations ever built, with its intricate bas-reliefs, strange acoustics and magnificent soaring towers. Angkor Wat, originally named Vrah Vishnulok - the sacred abode of Lord Vishnu, is the largest temple in the world. It was built by King Suryavarman II in the 12th century. The Sanskrit Nagara (capital) was modified by the Cambodian tongue to Nokor and then to Angkor. The word Angkor is derived from the Sanskrit word 'nagara' meaning 'holy city'. Vatika is Sanskrit word for temple. "The city which is a temple," Angkor Wat is a majestic monument, the world's largest religious construction in stone, and an architectural masterpiece. The Khmers adhered to the Indian belief that a temple must be built according to a mathematical system in order for it to function in harmony with the universe. Distances between certain architectural elements of the temple reflect numbers related to Indian mythology and cosmology. The sheer size of the place leaves visitors in awe and the complex designs illustrate the skills of long gone priest architects.
