This recently renovated structure, resplendent in red, gold and polished black columns, has quite a few more aliases, such as Hock Teik Cheng Sin, Poh Hock Seah, Hokkien Kongsi and Tong Kheng Seah. Why so many names? Well, besides serving as a temple and assembly hall, this building has also been the registered headquarters of several secret societies. Each society occupied a different portion of the temple, which became a focal point during the 1867 riots. The fighting became so intense that a secret passage existed between here and Khoo Kongsi for a quick escape. While you search for the corridor, be sure to admire the gilded filigree and lacquered roof beams that give this once underground HQ so much Imperial Chinese vibe.
