Olympic Stadium

Known collectively as the National Sports Complex, the Olympic Stadium is a striking example of 1960s 'New Khmer' architecture and includes a sports arena and facilities for boxing, gymnastics, volleyball and other sports. Turn up after 5pm to see countless football matches, pétanque duels or badminton games. It's also a popular spot for sunrise or sunset mass musical aerobics.
