Somdet Phra Sri Nakharin Park is located on the city island in the Historical Park at Pratu Chai sub-district. It can easily be accessed via U-Thong road. Somdet Sri Nakharin Park is "a park within a park", as it is part of the Ayutthaya Historical Park area and covers a vast stretch of land on which numerous restored ancient monasteries can be visited in a lush park environment.
Somdet Phra Sri Nakharin Park was set up in honor of the late H.R.H Princess Sri Nagarindra Borommaracha Chonani, the mother of HM King Bhumibol Adulyadey (Rama IX). She was a very beloved woman all over Thailand. The Moken sea nomads in the southern Thai islands still refer to her fondly as Somdet Ya, roughly Royal Grandmother, while Northern hill tribe people called her Mae Fa Luang (Royal Mother of the Sky). She has also been fondly remembered as Princess Mother. She died on 18 July 1995 at the age of 95, and her funeral took place on 10 March 1996. A commemoration monument is set up in the middle of this park.
