Comprising the Upper Reservoir (constructed in 1931) and the Lower Reservoir (constructed in 1932), Aberdeen Reservoir was built to augment Pok Fu Lam Reservoir and solve the problem of water shortages in the western part of Hong Kong Island. It became the fourth and last reservoir ever built on Hong Kong Island after Pok Fu Lam Reservoir, the Tai Tam Group of Reservoirs and Wong Nai Chung Reservoir.
4 Historic Structures of Aberdeen Reservoir were declared monuments in 2009.
