Khlong Ong Ang (Thai: คลองโอ่งอ่าง) is a canal (khlong) that forms part of the outer moat (Khlong Rop Krung) and marks the eastern edge of Rattanakosin Island in Bangkok.[1] In 2020, the canal was restored by the Bangkok Metropolitan Administration (BMA) to feature a walking street and night market.[2][3] The restoration won a 2020 United Nations Human Settlements Programme (UN-Habitat) Asian Townscape Award.[4] The Klong Ong Ang Walking Street is located along both sides of the canal, from Saphan Han Bridge to Damrong Sathit Bridge.[5]
