That attraction 'castle' is a stave church, which are typical for the real Norway.
I'm going to be a pest and say that this is what the princessification of Norway has done. Once the Stave Church housed an exhibit about stave church architecture. Which gave guests, children, a feel for the real thing. Nowadays it houses cartoons, leaving guests utterly uninformed, even misinformed. Swell place to take one's kids.
In effect, the EPCOT Stave Church IS the Disneyfied version, IS the fantasy world inspired by the actual Norway. Arendelle by contrast is an imaginary fantasy cartoon land, which happens to have a passing resemblance to Norway and the Nordic area because some inspiration was drawn from that. The Disneyfied version of Norway is being Disneyfied, until people mistake the princess toonland for the real thing.
