CLICK shot to upload, then I suggest you put it into toggle mode (bottom R). This makes it much larger. Then CLICK and hold and you can move the Stones in any direction.
A cist is a small stone-built coffin-like box or
ossuary used to hold the bodies of the dead. Examples can be found across
Europe and in the Middle East. A cist may
have been associated with other monuments, perhaps under a cairn or long
barrow. Several cists are sometimes found close together within the same cairn
or barrow. Often ornaments have been found within an excavated cist, indicating
the wealth or prominence of the interred individual.
I hope you enjoyed seeing this and also thanks to David for giving me permission to use this.
