Today we visited the archaeological site of Delphi. Delphi is definitely one of the most amazing archaeological sites to which I have ever been. It is not the biggest. Olympia and the Athens Acropolis are probably bigger, and both of them are very impressive. I think what I found so awe-inspiring about Delphi was not just the ruins, which are impressive, but also the setting. It is nestled into the mountains, and it reminds me of Machu Picchu. As an engineer, I haven’t stop being impressed with the construction of these sites, and at Delphi, I found the Polygonal Wall to be just amazing. Polygonal Wall is built of carved stones set on top each other without any mortar.
