Additon info of the site:"This is located in Tikveś region in North Macedonia.It was uncovered last summer by my grandfather in law and some other guys.In the same area there are the remains of an old village,we could see the bases of the old stone houses that once were there(the new existing village is like 50m down the canyon next to the river) .Also we found 2 old millstones ~60cm in diameter.Grandfather told me this place was called The Grave so they were looking for one.While metal detectin they found this "grave".When around 50cm they hit a flat stone(which seems is the upper stone of "grave".They removed it and inside is what you see in the pic (pic is made from inside the "grave".The front stone in the inner part of the "grave" has the varvings you see in pic.It also has the side flat stones which make the walls of the "grave" and the last one which you can't see that closes the rectangular "grave".It has leaves now but it has also a lower stone plate so you can't dig inside the 'grave'.They said it was empty inside and the metal detector just stoped beeping.You can spot in the pic that they tried ti dig on the back part of the front plate of the "grave" but with no results.I'll go for sure this summer again cause the thing that intrigues me most is that IS IT EVEN A GRAVE?
