The century-old monument, Duddell Street Steps and Gas Lamps in Central, was severely damaged when Super Typhoon Mangkhut hit Hong Kong on 16 September 2018. The Antiquities and Monuments Office conducted exhaustive research to unearth the monument’s history, and was determined to adhere strictly to the conservation principle of using original craftsmanship and materials, supplemented by advanced 3D scanning technology, so as to ensure the faithful restoration of the monument. With the assistance of the Highways Department and The Hong Kong and China Gas Company Limited (Towngas), the expertise of the UK-based supplier of the original gas lamps, and the unfailing support of the Antiquities Advisory Board, the restoration was completed on 23 December 2019.

The exhibition showcases exhibits using photos and video to share with the public the details of the restoration work, including the implementation of the key conservation principle, and integration of traditional craftsmanship and advanced technology.
