The bell also gave the temple its name, as Rakang is the Thai word for bell. During the renovations done by King Rama I a huge bell was found and moved to Wat Phra Kaew, five smaller bells were installed in the temple as replacement. It dates back to Ayutthaya times, when it was named Bangwayai. Wat Rakhang Khositaram Woramaha Wihan is a major temple near the Chao Phraya river. In the Suwannaram Witthayakhom School next to the temple is also the district museum. The temple is most famous due to the murals, which are considered the most artistic of that time. It was a royal cremation site in the early Bangkok period, however the cremation site was demolished and used to be the location of the Bangkok Noi district office. King Rama I had the temple restored and renamed it to its present name. Wat Suwannaram Ratchaworawihan, also located at the southern rim of the Khlong, was originally called Wat Thong and dates back to Ayutthaya times. The cleared space is allocated for expansion of the Siriraj hospital, however currently only used as a parking lot. In 2003 the railway station was moved one kilometer westwards and the old building is now unused.

It was rebuilt in same style after the war. During World War II the Japanese used it as their logistics base and thus the station was destroyed. The hospital also houses several exhibitions, like the forensic museum in the Siriraj Medical Museum.ĭirectly next to the hospital is the Bangkok Noi Railway Station (or the former Thon Buri Railway Station), which serves the trains to the west, especially to Kanchanaburi.

It was originally named Wang Lang hospital, as it was built on the site of a palace (Thai: Wang), it was later renamed after Prince Siriraj Kakuta Bhandu, the beloved son of King Rama V, who died of dysentery only 18 months old. On the other side of the khlong is the Siriraj Hospital, which was the first western hospital in Thailand. The National Museum of Royal Barges on the northern rim of Khlong Bangkok Noi near its mouth to the Chao Phraya River houses the royal barges, used for Thailand's Royal Barge Processions on very special events, like 200th anniversary of Bangkok or the 60th anniversary of the accession of King Bhumibol Adulyadej. The slogan of the district is Resonant Wat Rakang, historical Wang Lang, Royal barges and railway are renowned, lively khlong, inherited stone-polished bowl, Buddha image cast, and abundant ancient wats.

The district seals shows the head of the royal barge Sri Suphunahongsa. On 12 December 1991 a small part of Bang Phlat district was moved back to Bangkok Noi, creating the new Arun Ammarin sub-district. Later on 9 November 1989 the Bang Phlat district was created from four of Bangkok Noi's sub-districts, leaving Bangkok Noi with four remaining sub-districts: Siri Rat, Ban Chang Lo, Bang Khun Non, and Bang Khun Si. It became a khet in 1972 when Thon Buri and Bangkok were merged. Originally named Amphoe Ammarin, it was renamed on 11 July 1916 to Amphoe Bangkok Noi to match with the historical name of the area.

Bangkok Noi was established as an amphoe on 15 October 1915.
