ThisWharf architecture chapter takes the 17 wharves along the Inner Harbour of the Macau Peninsula from Barra (媽閣) to Lam Mau Tong (林茂塘) as the objects of study, systematically revealing the coupled evolution of port–city relationsPort–city relations, industrial organization, architectural types, and governance mechanisms. In the first half of the twentieth century, light industries such as firecracker production and passenger–cargo shipping routes shaped the Inner Harbour into a typical maritime cultural landscape. From around 1948 to 1953, the typology rapidly shifted from timber pile trestles to reinforced-concrete “box-shaped” structures. Starting in 1966, cold-chain facilities were embedded and the functional orientation transformed into a composite of fishery, refrigeration, wholesale, and catering uses. In the 1980s, the government promoted unified roofing and land concession reconstruction, standardizing 34 old-style wharves, institutionally nesting with the public passenger transport franchise (1953–1964), differentiated supervision of hazardous goods, and shoreline governanceShoreline governance. In terms of scale, the majority had a frontage width of 15–33 m with dual berths as a typical configuration, and a unit berth width of 7–12 m. Based on these findings, this research proposes feasible conservation strategies such as compatibility restoration using washed granolithic plaster and masonry for “restoration in original style,” reinstatement of platform drainage and fender components, and preservation of parapet inscriptions and Sino-Portuguese nameplates. It further suggests a combined governance framework integrating functional zoning, municipal facilities, and revitalization, to support the holistic conservation of the historical shoreline of the Inner Harbour and the reconstitution of its waterfront public character.
