Ubonrat Bridge

Ubonrat Bridge, sometimes written as Ubolratana Bridge (สะพานอุบลรัตน์, ) is a historic bridge spanning Khlong Khu Mueang Doem (old city moat) in Rattanakosin Island or Bangkok's old town zone.

Background
The bridge was built in 1912 as a memorial to Princess Ubolratana Narinaga, the consort of King Chulalongkorn (Rama V). It was built on a former bridge called "Hua Takae" (หัวตะเข้, ), which means "the head of a crocodile".

The plaster banisters were designed in the Thai style with the name plate of the bridge set at the middle. It is now a recognised ancient monument since 1988 by the Fine Arts Department.

It serves to connect two roads along Khlong Khu Mueang Doem, Atsadang and Rachini Roads. At both ends of the bridge, there are two short roads named Phra Phiphit (west end) and Phra Phithak (east end), which are all named after King Phutthaloetla Naphalai (Rama II)'s son, because there used to be their residence in the vicinity during the early Rattanakosin period. It is considered a bridge over Khlong Khu Mueang Doem as well as other nearby bridges, such as Mon Bridge, Saphan Hok, Pi Kun Bridge, etc.
