From the Guidebook:
This stadium was originally
completed in 1923. It was partially redesigned and enlarged
for the 1932 Olympic Games. Both designs were by architects
John and Donald B. Parkinson. The coliseum has witnessed
many important sports, political, and historical events.
When the games of the XXIIIrd Olympiad began here on July
28, 1984, the coliseum became the first stadium in the
world to host the Olympic Games twice.
