This is the famed Lion’s gate at the entrance of the ancient city of Mycenae.  The citadel is roughly 3600 years old.  This is also the city of the famed King Agamemnon, as made famous by Homer.  The capstone above the gate depicts two (lions?) creatures that appear to be lions.  This city controlled much of the peloponnesia for centuries.  Agamemnon, from what we know of him, exercised much power over Hellas.  His tomb is a short way away, and it is a mound type “bee-hive” tomb.  Of course there was nothing left, because the tomb had long been picked clean of treasures by grave robbers.  But back to the city walls.  The Myceneans had discovered how to build huge walls that baffled the classical Greeks.  They decided that the walls were cyclopean.  That cyclops giants must have built it because they were too large to have been built by human hands.  Very amazing.  It’s easy to see why the Myceneans were able to exert such influence on the area.
