What is the "Dungeon of the Jinn" located at the beginning of the Haram in Mecca?

The place mentioned is where the Prophet, peace and blessings be upon him, met with the jinn and spoke to them. This occurred when the Companions missed him, and then he returned and informed them that the caller of the jinn had come to him, so he went with him and recited the Qur'an to them. He also showed them their traces and the traces of their fires, and explained to them their provisions and the fodder for their mounts.
