As we hiked through the ruins at Delphi we found signs pointing upwards to a stadium, so we decided to see what it was. As we hiked higher and higher we passed people stopping and turning around before reaching the top. By the time we arrived there were only about 3 other people who had also made the trek. But it was worth the work when we stepped into a huge stadium. It was built in the 5th c. B.C. and it was remodeled several times during the centuries. Its present form is from the 2nd c. A.D. It could seat around 6500 spectators, and it was used for athletic events and for music festivals. Its track is about 550 feet long.
