Syonan Jinja (昭南神社, Shōnan Jinja, lit. "Shōnan Shrine") was a Shinto shrine at MacRitchie Reservoir, Singapore. Built by the Japanese Imperial Army during the Japanese occupation of Singapore in World War II, the shrine was destroyed directly before British forces re-occupied Singapore.Located deep inside the Central Catchment Nature Reserve (CCNR), the National Heritage Board (NHB) declared the site a historic site in 2002, although no plans have been made public so far to develop or make any significant changes to the site since the war.
