This is a scene I was thrilled to see again today! The four remaining columns of the Temple of Castor and Pollux, built in the 5th century BC and reconstructed in the 19th century. We walked the full 2 kilometers of Valley of the Temples that sits on a ridge with sweeping views of the sea. It’s hard to imagine that at one time Agrakas, as the Greeks called it, was 200,000 inhabitants strong.
