Quick Summary

Khlong Phadung Krung Kasem is a canal in Bangkok, Thailand, that was dug and fortified during the reign of King Rama IV (1851–1868). It runs parallel to the city's first canal and was intended to serve as a defensive moat. A long canal connected it to the port area, allowing smaller boats to bypass a bend in the Chao Phraya River. The earth from this excavation was used to build a path atop it, which is now a major highway. This canal is part of Bangkok's extensive canal system, which historically served as vital waterways for transportation and drainage.12
