Bang Khun Phrom (Thai: บางขุนพรหม, in Thai pronounced as /bāːŋ kʰǔn pʰrōm/) is a khwaeng (subdistrict) of Phra Nakhon District, in Bangkok, Thailand. In 2020, it had a total population of 4,063 people.[2]
Formerly the area known as Ban Lan (บ้านลาน, in Thai pronounced as /bâːn lāːn/), a place that was a hub of palm-leaf manuscript shops. The name Ban Lan literally means "community of palm-leaves". The palm leaves sold at Bang Khun Phrom were imported from Pak Kret's Bang Tanai.
Later, its name was changed to Bang Khun Phrom after the name of Khun Phrom, a nobleman who had a monopoly on the palm-leaf trade in this area.[3]
In the past, Bang Khun Phrom area was as wide as the western side of Samsen Road, the location of Wat Sam Phraya and Bang Khun Phrom Palace. The result of the administrative division of Bangkok causing both to be in the present Wat Sam Phraya Subdistrict.
Bang Khun Phrom, in the perception of Thai people, is known in terms of being the location of the country's first television station, Channel 4 (present-day Channel 9 MCOT HD), which has been in operation since 1955, therefore it is familiarly known as Channel 4 Bang Khun Phrom.
Originally, the area beside Wat Sam Phraya cut across Samsen Road to Wat Iam Woranuch and Wat Mai Amataros. There was Khlong Bang Khun Phrom running through it. It was a large and wide canal. Khlong Bang Khun Phrom was filled during the government of Field Marshal Thanom Kittikachorn as a road named Payap Road. Today it has been integrated into a part of Samsen Road.[4]
