Full title, "3,200-Year-Old Cyclopean Masonry Fortress Found in South Bulgaria, Shows Ancient Thrace Was Part of Mycenaean Civilization".

BTW, these don't look like walls, they look like natural formations to me.

It's not the right era for this thread, but while I'm thinking about it, many years ago I read a book about Heinrich Schliemann who discovered ancient Troy or what remained of it. Don't remember one detail which is why I don't read books any more, but he did find Troy.

I don't know much about a lot of archeology but read things that capture my interest like a very early Christian site discovered in Israel on the grounds of a prison.

Here's a video about Schliemann, a 3-part series, all short, will watch the other 2 later, was up until the wee hours watching a live version by National Geography about theories of the creation of the universe and related matters.
