Most Popular Temples
The three best known temples within the historical park are:
- Wat Maha Tat: This is the temple with the head of a Buddha statue around which the roots of a tree have grown. Burmese invaders cut off the heads of the statues at this temple, and many others in Ayutthaya, in act of deliberate vandalism when they invaded the city in 1767.
- Wat Phra Ram: This temple has a very large central prang (Khmer style tower) which is the tallest structure in the historical park.
- Wat Phra Si Sanphet: Considered by many to be the best temple in the historical park, Wat Phra Si Samphet features three large prang in a row. The prang towers have been aligned to the position of the stars and sun in a similar way to other great temple complexes such as Angkor Wat.
