There’s something a little steampunk about this corner of Duddell Street. Surrounded by the restaurants, galleries and burgeoning businesses of Central, this set of granite steps is home to the four remaining gas street lights in Hong Kong, which are today declared monuments. While the exact construction date is unknown, it’s posited that the steps were created sometime in the late 19th century. Today, the gas lamps are automatically powered by Towngas, flicking on and off promptly at 6pm and 6am every day. In the past they were, of course, lit and extinguished by hand.
