The famous Angkor Wat is truly an engineering miracle by definition. It is a temple that floats on a swamp, supported by subterranean water. The gigantic construction has been built under the orders of an autocratic king, Emperor Suryavarman II, to honour God Vishnu, whom he has chosen as his patron. It was also believed that it would act as a gateway to heaven for the king, after his demise. Angkor Wat can be roughly interpreted as the "temple city," a marvellous creation of the human, which has surpassed many construction barriers in a formidable manner. The iconic temple was initially a Hindu shrine before being rechristened as a Buddhist place of worship.
