Four lime kilns once stood on the eastern shore of Hoi Ha Wan; two remain relatively intact. The local lime industry operated broadly from 1800 to 1939. Their position along the bay places industrial remains within a shoreline now known for a very different relationship with the sea.

Hoi Ha Wan’s Lime Kilns and Coastal Industry
Four lime kilns once operated on Hoi Ha Wan’s eastern shore. Their surviving structures connect a historic shell-and-coral industry with the bay’s protected marine landscape.

From shells and coral to lime
The kilns processed oyster shells or coral skeletons into lime used in construction and agriculture. Marine material became a practical product for building and farming. The record describes the industry at the bay level; it does not assign a particular batch of shells to any one kiln.
A working coast, a protected bay
Hoi Ha Wan was designated a marine park in 1996. Coral communities, mangroves and varied marine life shape the area today. The kilns preserve a trace of coastal production, while the marine park protects habitats along the same shore: two chapters in the changing use of the bay.
