Not Surprisingly Sandstone

Pentalofos Sandstone from here in Greece. It looks, not surprisingly, like sand on a beach of today, but is indeed about 60 million years old.

Borrowed from the earth, this is the traditional building stone for houses, churches and bridges all over Northern Greece, some of theses structures dating to the Byzantine Period.

History built on a historic stone.
