This is certainly one of the greatest paper model websites and well worth mentioning now and then. It was one of the first such websites I ran across when I first got into paper modeling back in the early 00s. For awhile it appeared to disappear, but has managed to turn up again with everything intact.
While they do list a lot of models sourced at other sites, DE itself hosts some of the coolest paper models period-- most notably the Sleeping Beauty Castle, Main Street Station and the 20K Nautilus. I just noticed DE has added a few Star Wars and Marvel Comics related models to their list. The list could stretch a lot further if they try list them all (been there, doing that).
I'd built the Haunted Mansion (Disneyworld version), it went together pretty well, but didn't survive the giant feline attack of early 2019. Two daughters visiting, both brought their cat. Cats.... didn't like each other.
The Horror!! Thanks for posting this, that site is amazing. I would like to have seen a picture of the ruins, you may have been able to make a diorama out of that, with some well executed clipping, and restructuring. Ruined castles are cool.
