The Chapel of the Holy Cross
By 1231 the Mezquite had been reconsecrated as the Chapel of the Holy Cross (Ermita de la Santa Cruz) and was owned by the Knights of the Order of St John.
I don’t know what the cellar in what is currently known as the Mezquite de la Luz was originally used for – perhaps only storage, as I describe it here. But it still exists, and you can look down into it through a hole in the floor.
The door is roughly as I have it too. It is not possible to enter it, so other details are fanciful.
