Bueng Phra Ram, named after Wat Phra Ram in its vicinity, is located in the center of Ayutthaya in the Historical Park. The former marsh is
one of the 95 sites on the listing compiled in 1987 to be registered as UNESCO World Heritage in December 1991. The site, called in the old
documents Dong Sano or sometimes Nong Sano, has been largely altered over the years. Bueng Phra Ram was restored and turned into a
park in the period 1956-1957 during the time of Field Marshal Phibunsongkhram.
