The Cercle Sportif was built in 1929 near to Wat Phnom on what was then Avenue Joffre. There were tennis courts as well as the large pool. Situated in the French quarter, it was enjoyed by the elite members of the protectorate and their families for many years. After independance it was re-named the Club Sportif Khmer.
On 21st April 1975, former Prime Ministers Long Boret and Sisowath Sirik Matak were executed on the grounds. It was demolished in the early part of this decade to make way for the sprawling US Embassy which was built on the site.
The Cercle Sportif in Battambang was inaugurated in 1965. It originally had an Olympic sized pool, but when it was refurbished a few years ago this was made smaller, and now the diving board is far from the water.
The Phnom Penh Sports Club (previously called the VIP Club, the current VIP club near Norodom Boulevard and the PPSC are managed by the same company) on St. 271, south of Psah Tuol Tom Pong, was formerly the residence of Marshall Lon Nol. It apparently had a large underground bunker built below it. In 1974 Khmer Rouge artillery landed close to the house, although he wasn't there at the time.
