The olive oil reserves contain jars and drums of olive oil pressed from the groves at Lalish. There are two dark chambers, the first being larger and the second much smaller.
Upon entering the olive oil stores, there is a rock to the left. On the Yezidi New Year, people make a wish and throw a cloth onto it. If the cloth stays then their wish will be granted.
The second chamber contains a candle flame that is kept lit forever. It is not allowed to ever extinguish. Beyond this chamber is the tomb of Sheikh Abu Bakr.
