Bang Kho Laem was formerly a part of
amphoe Ban Thawai in
Phra Pradaeng Province. Ban Thawai was later reassigned to
Phra Nakhon Province, and renamed amphoe
Yan Nawa. When Phra Nakhon and Thon Buri were combined into a single province in 1972, the names of administrative units in the newly combined capital were changed from
amphoe and
tambon to district (
khet) and sub-district (
khwaeng). Thus, amphoe Yan Nawa (อำเภอยานนาวา) became khet Yan Nawa (เขตยานนาวา). Due to population increases, on 18 April 1989, Yan Nawa Branch 2 (Khwaeng Bang Kho Laem) was established as a second administrative unit within the Yan Nawa District, overseeing three sub-districts: Bang Kho Laem, Wat Phraya Krai, and Bang Khlo. It became a separate district on 9 November 1989, called Bang Kho Laem. The name
Bang Kho Laem literally means "a place of narrow neck", referring to the Chao Phraya River that bends sharply here. It has been noted that it may have a
Bangkok Malay origin. Within
Soi Charoen Krung 103 is a long-established
Muslim community known as Suan Luang 1. In the past, the waterway here was a large
khlong (canal) with clean water where children could swim, and ships would pass through. It is now just a small waterway. Since 2013, the area has been developed into a
waterfront market featuring about 100 street food stalls, all of which are
halal, although some traders are non-Muslims. ==Administration==
