This is Kallang River. How the name Kallang came about is very interesting.
The Biduanda Orang Kallang, a people group found in Java, constituted at least 50% of the 1000 residents found in Singapore at the time of Raffles' landing. They were a shy, primitive river people who were boat-dwellers, and had lived in the swamps at the mouth of the Kallang River, which thereafter took on their name. (Source: Infopedia )
Today the Kallang River has been cleaned up from a swampy river to a very beautiful and clean river. There are many private condominiums on the waterfront and they are very beautiful and of course expensive.
