Kallang is a planning area and residential zone located in the Central Region of Singapore. Development of the town is centered around the Kallang River, the longest river in Singapore. Kallang Planning Area is bounded by Toa Payoh in the north, Geylang in the east, Marine Parade in the southeast, Marina East in the south, the Downtown Core in the southwest, Rochor, Newton in the west, and Novena in the northwest. Throughout its history, Kallang was home to several national landmarks, some of which were built along the banks of the Kallang Basin, including the old National Stadium as well as the country's first purpose-built civil airport, the Kallang Airport. The famous Kallang Roar and Kallang Wave have roots traced to the former National Stadium, which hosted 18 National Day Parades, as well as numerous notable cultural and sporting events. As such, Kallang played a pivotal role in Singapore's aviation and sporting histories. Today, Kallang is best known as the location of the Singapore Sports Hub, which is home to the new National Stadium and the Singapore Indoor Stadium. The new National Stadium hosted the National Day Parade in 2016, while the Singapore Indoor Stadium frequently hosts world-class concerts and performances by renowned artists and musicians from around Asia and the world. Etymology The area of what is now Kallang first appeared in an 1830 survey map of Singapore as "Kilang". By 1838, the place name was spelled as "Kelang". The modern-day "Kallang" is in use since 1842, even though the alternative spelling "Kalang" is also utilised in some instances. The Chinese and Tamil names for Kallang are "加冷" and "காலாங்" respectively. Both are direct transliterations of the English/Malay name. The Chinese word "加冷" is generally based on Cantonese (pronounced as "加冷 gaa-laang") transliteration of the word "Kallang". Kallang was also nicknamed "火城" ("fire city") by the Chinese community because it was the site of the Kallang Gasworks.
