Here's a picture of the columns rebuilt around the courtyard of the Palaestra (the wrestling school).
The Temple of Zeus contained a statue of Zeus seated on a throne. The seated Zeus was twelve meters high, and made of gold and ivory. It was one of the wonders of the ancient world. It was removed to Constantinople where it was destroyed by fire in 475 BC. These are the columns that have fallen next to the temple. The senior teacher of the group said that they have deteriorated since the first time she visited the site. Imagine that -- they've survived thousands of years and modern acid rain has worn them down visibly within her lifetime!
They were restoring a column at the Temple Of Hera. The scaffolding held a bunch of pulleys which gave these guys an amazing mechanical advantage. They could pull down on a chain and the chain would keep falling on its own momentum for a while while raising the stone an imperceptible amount.
We all posed at the starting line in the stadium. The start and finish lines were made of stones and they were still there. We raced, too. I know the women were hampered by their skirts and I think Dane might have been pacing himself with the student who was with us. When the women asked who won and guessed Dane, Dane said "No. Adam won. The Americans are always winning." We all laughed.
