Khlong Khu Mai Rong, free translated the "Canal of the Crying Wood", was situated off the city island in Tha Wasukri sub-district opposite Khlong Tho (also called Khlong Chakrai Yai).
The waterway flowed on the northern side of the old Lopburi River (presently renamed Khlong Muang or City Canal) opposite the Grand Palace between Wat Choeng Tha and Wat Phanom Yong. The canal was in fact part of the ancient Dock of Royal Barges.
Khlong Khu Mai Rong formed a reversed U, containing within the landing of the barges. Its name was probably derived from the creaking of the wood from the wooden boats.
A market was held behind the Dock of Royal barges in former times. “Talad Wat Khu Mai Rong” was one of the 32 land markets outside the city of Ayutthaya. The name of the marker suggests that there must have been once a temple in the vicinity of this canal called Wat Khu Mai Rong, though no traces of the latter has been found as yet. [1]
