Stone Bridge Tower

 Stone Bridge  Tower  Arcing skyward out of the solidity of the Stone Bridge, this structure is a manifest mark of the castle's physical roots, as the closest thing to non-magical so permeated a place may offer. It is the repository for those simple objects which the inhabitants occasionally, but when they do, desperately, need. Buckets and boxes, carefully wrapped against mystic intrusion, rub shoulders with a few basic boats, a stockpile of wood and all the tools a handyman could ask for. If magic ever fails, this provision may well be the saving of Hogwarts.
