Mycenae

All the awfulness in the tale of "Atreus and Thyestes" goes down in the city of Mycenae. Archeologists unanimously agree that Mycenae was a real place, and that it was majorly important back in ancient Greece. They've even named a whole period of Greek history the "Mycenaean Period" because the powerful city totally dominated the culture. The ruins of a palace still stand on the sight that was once Mycenae, and many amazing ancient artifacts have been found there. There's even an ancient tomb there called the Treasury of Atreus, although most all archaeologists agree that it was built a long time after Atreus would've been around.
