mmm...
Isn’t this period usually called Mycenean? I thought Bronze Age Greece was the Classical Period.
The Mycenaean era is aka the age of heroes; it ended rather rapidly, and due to invasion in most places. The old Mycenaean sites were either abandoned, or the rebuilding went up immediately atop the ruins, without any stratification or break in the action.
In Mycenaean Sparta, there’s barely any known traces of what must have been a big palace, perhaps because the available hilltop wasn’t very large and had to be supplemented with landfill. The landfill eroded away, or was carried off for reuse when the “grandsons of Hercules” arrived, killed off the Mycenaean royal house, and began their implementation of their charming euthanasia and pederasty based freakshow.
In Pylos, which was the home of Nestor (sez the Iliad), the Mycenaean archive was found on day one when Blegen started his excavation; there’s one partial tablet that ends in a scrawl, as if the scribe suddenly had to join the defense of the unfortified city. Pylos’ location was remembered down through the ages, but never rebuilt. During one of their wars to enslave their neighbors, the classical era Spartans conquered the area, and eventually lost a land battle to the Athenians during the Pelop. war.
