This tomb is a bit unusual in that all of the stone around it has been carved away and the large block of bedrock that remained was carved into a house (or temple?) like tomb. On its left side the (false) projecting beams are visible, as they are just under the room.

This necropolis (city of the dead) dates to the fourth century B.C.
