Koubbat as-Sufara is a hall that was once used for the reception of foreign ambassadors, but the creepy crypt below is an even better sight. Through it was only used for food storage, it has the atmosphere of somewhere more likely to be haunted than a simple granary.
There were very few visitors present during my time there, so it was relatively easy for me to run around popping off flash bursts to light this lengthy hall.
