The name "To Kwa Wan" literally means "Potato Bay", named for the sweet potatoes formerly grown here by local
Hakka people. From the 19th century, a nearby granite quarry provided construction materials, including for the development of
Kai Tak Airport. At the time of the 1911 census, the population of To Kwa Wan was 1,072. The number of males was 766. After World War II, light industrial units sprang up, making products such as toys and textiles. Housing rose concurrently with factory buildings, and in the 1970s
the area's public housing estates were built to relieve pressure in other crowded areas of Kowloon. ==Green space==
