Wat Maha That in Ayutthaya is where the iconic Buddha head statue is located.
Wat Maha That is located to the east of the grand palace. It is the royal temple and most sacred in Ayutthaya during the glorious time. Buddha relics were enshrined in the Maha That Chedi (the principal pagoda). This monastery was once the residence of the Supreme Patriarch.
Ayuthaya chronicle said Mahathat Chedi was initially built in the reign of Phra Borom Rajathirat I (Khun Luang Pha- Ngua_ in 1374 and completed in the reign of King Naresuan.
In the reign of King Song Tham the principal pagoda collapsed through the foundation but it was restored later in the reign of King Prasat Thong.
This monastery was destroyed and had been burnt in the last war between Ayutthaya and Burma in AD 1767. It was left in ruins.
