Khlong Maha Sawat

Khlong Maha Sawat (pronounced [kʰlɔ̄ːŋ mā.hǎː sā.wàt]), also known as Khlong Chaiyaphruek (pronounced [kʰlɔ̄ːŋ t͡ɕʰāj.jā.pʰrɯ́k]), is a khlong (canal) in Thailand. It is a man-made waterway dug in 1859–1860 in the reign of King Rama IV. Today it is listed by the Fine Arts Department as a national heritage site. It starts from Khlong Lat Bang Kruai (Khlong Bangkok Noi) near Wat Chaiyaphrueksamala, flows along the border of Nonthaburi's Bang Kruai with Taling Chan and Thawi Watthana of suburban Bangkok, then flows through Phutthamonthon to meet the Tha Chin River at Ngio Rai Subdistrict in Nakhon Pathom's Nakhon Chai Si District. Its length is 28 km (17 mi). Note: Khlong Maha Sawat and Khlong Prapa Maha Sawat are two different canals.
