Perched above the streets of Tai Hang, the 91-year-old Haw Par Mansion has stood as a watchman to Hong Kong’s evolving history. The mansion and its front garden are the only remaining sections of what was once a sprawling estate and theme park built in the 1930s by the Aw family of Tiger Balm ointment fame. They are striking examples of the period’s architectural hybridity, often called the Chinese Renaissance style.
