The district takes its name from Rong Mueang Road, a short route that runs through the area. The road runs parallel to the Bangkok railway station side to end at Rama I Road on the Kasat Suek bridge, a distance of about 900 metres (2,952 ft).
This road was named in honour of Phraya Indra Dhibodee Siharat Rong Mueang (M.R. Lop Suthat), a nobleman during the King Rama V's reign. He was one of the nobles of those days who helped build many roads in Bang Rak District for real estate investment such as Si Phraya, Decho, and Surawong. Construction began in 1902 and continued until the opening ceremony on 29 March 1904.[2]
The area is an amalgam of at least four communities: Trok Salak Hin, Wat Duang Khae, Flat Rot Fai, and Charat Mueang. Between them, they boast seven interesting landmarks.[4]
