At the time, it sat on the banks of the Singapore River, close to a small islet called Pulau Saigon. The islet has since been dug out and a part of the river filled in so that Tan Si Chong Su is now set back from the water. The funds needed to build the temple were donated by two men from the most prominent Tan families in Singapore Tan Kim Ching and Tan Beng Swee. Tan Kim Ching was the eldest son of philanthropist and businessman Tan Tock Seng, whose significant fortune he inherited. Tan Tock Seng is perhaps best remembered for his contributions to public health care. Tan Beng Swee was the son of Tan Kim Seng, also a successful businessman and a leader of the Chinese community. Of Tan Kim Seng's many civic projects, arguably the greatest was setting up of the city's first fresh water supply lines.
