I will not be moved

The 15th c. Rosslyn Chapel has dozens of platforms created to support statuary, inside and out (see orange blobs), but no one's home! Some theorize that 17th c. parishioners of one sect, anticipating plunder by a reforming sect, spirited away the occupants of the niches and hid them --too well! Since the chapel was not completed before the death of the man who funded it, it's possible some niches were never occupied. An added insult to the building, Scots complain, was that Cromwell used the building as a stable.
What's interesting is the stones that were not removed: the carved support stones for the statuary and stone members of arches that support openings. They had been carved into figures of a secular or pagan nature, or events any flavor of plunderer might fear or respect. Being structurally riskier to knock down, that green man or the bagpipe-playing figure remain in place today. Because they were like motherhood and apple pie are to Americans, might masons have preserved deeper-seated subject matter according to the structural role a stone played? Did these icons' deeper cultural roots make them structurally safer?
Possibly a worst offense to the building took place in the 1950's. In a preservation attempt gone-wrong, a thin coat of cement was applied to the entire structure, inadvertently cloaking and suffocating the colorful, living rock within its own grey baggie. In what some say is perpetuating another false image,  Hollywood is providing funds to repair.
