Built in the 1960s for the Asian Games that never happened, this interesting complex in the Modern-style has been sold off to the Taiwanese, in a murky deal by the Cambodian government. The new owners have renovated it and it has begun to be used once again as a venue. However in the evenings a walk around the top perimeter is worthwhile: you can see hundreds attending exercise and dance classes, and get a view of the abandoned track below. There is also an Olympic-size swimming pool and diving pool with a 10 m platform open to the public opposite the main building, across the track.
