Eng Aun Tong (Hall of Everlasting Peace) was built by Aw Boon Haw in the 1920s as a factory to produce the internationally renowned Tiger Balm. This is one of the few flat roofed buildings from before World War II. On the roof is a six-sided pavilion, a reference to the six-sided glass bottle that Tiger Balm is sold on.
