To have a piece of land constructed into the shape of the country is a great thing for that country. Ancient Siam is a park constructed under the patronage of Lek Viriyaphant. The park spreads over 200 acres (0.81 km2) in the shape of Thailand. His reason behind this idea is one that deserves to be respected by Thais all around the country. During his research, Lek Viriyaphahet, found most structures around Thailand being severely damaged over time and decided to create a new miniature to save the original structures when possible.Ancient Siam is dubbed as the world's largest outdoor museum. Situated close to the Crocodile Farm in Samut Prakan province, the vast place features 116 structures of Thailand's famous monuments and architectural attractions. The grounds of Ancient Siam correspond roughly to the shape of the Kingdom, with each of the monuments lying at their correct places geographically. Some of the buildings are life-size replicas of existing or former sites. The replicas were constructed with the assistance of experts from the National Museum to ensure historical accuracy. Outstanding works include the former Grand Palace of Ayutthaya which was destroyed by the Burmese during the invasion in 1767, Phimai Sanctuary in Nakhon Ratchasima, and Wat Khao Phra Viharn on the Cambodian border.
