The Building being used by the Danish Seamen's Mission at No. 10 Pender Road was built in 1909. It was called the 'Golden Bell' and was built as the home of Mr Tan Boo Liat, a grandson of Mr Tan Tock Seng, the philanthropist whose name the famous Hospital was named after. Mr Tan B L sold the 'Golden Bell' some time after it was built. It is recorded that Dr Sun Yat Sen spent a night in the "Golden Bell" during a visit to Singapore.
