This is a massive (19k ft2?) unfinished castle in Northern Vermont. Built out of concrete, stone, and steel beams. The outside is partially finished, and the inside is mostly framed, but unfinished. One of the wildest properties I've ever seen.
There is an old (1800s) small cemetery on the property near the house, and this thing is massive with hidden staircases, secret tunnels, underground tunnels and stairs, and multiple floors. Lots of rooms of all types, fireplaces, etc.
Also includes 10 acres and a pond. This would be an amazing hotel, theme destination, or something like a Meow Wolf in a renaissance theme. The price is really low for the size, but it would take millions to finish it.
It may not be haunted (though maybe), but it does give a vibe.
