When the sun sets over Thailand, the Wat Chaiwatthanaram Buddhist temple lights up to welcome the night at the Ayutthaya Historical Park. These ruins are evidence of the area"s rich history as the capital of the Ayutthaya Kingdom, which grew in power between the 14th and 18th centuries to rule Siam, or present-day Thailand. Around 1630, Wat Chaiwatthanaram was built on the orders of the dynasty"s King Prasat Thong, to symbolize the center of the universe and connote his aspiration to become the future Buddha.
