Wat Mahathat in Ayutthaya, founded in 1374 by King Borommaracha I, is over 646 years old. It stands out with a main prang surrounded by smaller ones, symbolizing the universe in Buddhist cosmology. The temple is significant for Buddhists due to its association with the Ayutthaya kingdom's spiritual and political center. Its most iconic feature, a Buddha head entwined in tree roots, represents the interconnection of human and nature, embodying the enduring spirit of Buddhism.
