Wat Phra Si Rattana Mahathat known locally as ‘Wat Yai’ was founded in 1357. It is famous for its gold Buddha known as Phra Phuttha Chinnarat. This statue’s classical form is considered to be very beautiful, making the wat much revered throughout Thailand. The Buddha statue was cast between the 10th and 14th centuries, with some dispute over the exact date. The wat also features a Khmer-style Prang.
