Near my house at least two dolmens which I know. I'm not going to say what it is, but it's definitely something in that.
in this stone is the nearest, the lid someone rests))) By the way, they say the only thing that is oriented by the sun (the pyramid looks to the place where the sun rises into the equinox)
the second, next to grow oaks and chestnut yields good fruits
