Its name Lak Ha means "fifth milestone", refers to the fifth milestone of Khlong Damnoen Saduak, a khlong (canal) dug in the King Mongkut's reign (Rama IV) bridging rivers of Tha Chin to Mae Klong. The man-made straight line canal, approximately long, divided into eight milestones from the beginning to the destination at Bang Nok Khwaek Watergate, Samut Songkhram Province. It took two years, between 1866 and 1868, to complete.
