Graves of ancestors inside that caves?

While spending some time in nature, as I always do, in this path through the green and the cultivated fields, I found these sort of caves;

Like I said and like I showed in my previous videos this place is full of history of pretty much any age;

There are ruins of 5000 thousands years ago, which includes an archeological site full of graves, not quite far from here;

Plenty of ruins of the Roman Empire, since this was a former roman colon (if you are interested scroll down my channel, I ensure you that what I show is not that common);

War World II remains, of which I showed you a bunker and a kind of a workstation along the sea rocks;

I woulnd't exclude that these caves can be something like a Dolmen/ portal tomb, since like I said there are many of them;
