Wat Phra Si Rattana Mahathat
Wat Phra Sri Rattana Mahatat Woramahawihan (Thai: วัดพระศรีรัตนมหาธาตุ, also commonly referred to as Wat Yai) is a Theravada Buddhist temple (Wat) in Phitsanulok, Thailand, where it is located on the bank of the Nan River near the Naresuan Bridge.
The cloister of the temple was established in 1357 during the reign of King Maha Thammaradscha I of Sukhothai.
Wat Yai is famous throughout Thailand for its golden sculpture of the Buddha called the Phra Buddha Chinnarat (Thai: พระพุทธชินราช). Many Thai people consider the Chinnarat to be the most beautiful Buddha portrait in Thailand. It depicts Buddha in the posture of submission. Several faithful copies of the Chinnarat are displayed in other temples, including Wat Benchamabophit in Bangkok and Wat Saranat Thammaram in Rayong. Also, the Chinnarat is depicted on the official seal of the Phitsanulok Province.
The temple'slarge vihara has an immense main entrance with mother-of-pearl inserts donated by King Boromakot in 1756. Beyond the vihara is a Khmer style prang, the inside of which can be accessed via a stairway. The Prang is said to enshrine relics of the Buddha.
