The temple is set up on a hill overlooking the ocean. It's the southern most point from Athens and was a great lookout point for ships approaching by sea.
It's beautiful to see the way it's constructed - all the blocks put together just so.
I always find it interesting what changes and what doesn't - whether it's across cultures or over time. At Sounion, you can see all the graffiti people from long ago left. They carved their names into the marble in order to make their mark.
