Sa Kaeo - Sa Khwan
These two ponds are located in Tambon Sa Kaeo on the western side of town. Before approaching the city, turn right at 246th kilometre. It is believed that these two ponds contain sacred water once used for the coronation ceremony. The name of the province (Sa Kaeo) had been derived from this venue, whereby Somdej Chaophraya Maha Kasatsuk (King Rama I later) went to fight with the Cambodians, and stopped at this site to use sacred water to swear for the fighting courage.
