Saphan Hok (Thai: สะพานหก, in Thai pronounced as /sā.pʰāːn hòk/) is a bridge over the old city moat or Khlong Khu Mueang Doem in Bangkok's Phra Borom Maha Ratchawang and Wang Burapha Phirom sub-districts, Phra Nakhon district. The bridge is located right in front of the entrance to Saranrom Park.
Its name translates as "tipping bridge". It's a bridge that can be drawn up for boats passing through. Originally, it was a wooden bridge that was built from the same type bridge in the Netherlands. In the early Rattanakosin period, there were eight Saphan Hok in the area of Bangkok, in both the Phra Nakhon (Bangkok core side) and Thonburi sides. Today, only this one remains. In the reign of King Chulalongkorn (Rama V), the bridge was changed a reinforced concrete bridge to allow trams to run through. The bridge-foot has been modified to a ladder and this structure continues to this day.
Saphan Hok was restored as a pedestrian bridge in 1982 on the 200th anniversary of the Rattanakosin era, and it was rebuilt using the photographic document of the period.[1] [2]
