I am curious as to what a "stave church" is; the only definition of "stave" that I know, are those lathes of wood used in making barrels.
"Architecture" is not one of my strong suits; people are much more fascinating than buildings anyway.
I have heralded far and wide the architectural perfection of York Minster in England, promoting it as the best possible church in the world, and have gotten hollered down by barbarians, philistines, who insist I know nothing about architecture, and would not know "aesthetics" even if it slammed me in the face.
Bah humbug.
They are built using staves as supports much like longships.
