Tempio di Magna Mater in Rome

You're standing on the western slope of the Palatine Hill, at what's left of the Temple of Magna Mater, the Great Mother. The Greeks called her Cybele. Look at that big, rough block in front of you. That's the core of the podium the temple stood on. It was once covered in marble. Now you only see the guts of it: chunks of stone, thickly mortared together.
