If I had the means, I would restore it to it's proper state.
Restore it.. I would not want tourists trashing it.
When I visited Germany in 1992, my brother in law ran me through over a dozen castles. I had asked to see CATHEDRALS. Castles are boring. Tear it down, they're dull and there are too many. In England there's crumbly castles all over the place. A nice, modern resort, b and b style, with gently landscaped grounds and day trips offered to nearby historic locations, could be a hit with the honeymoon crowd.
You mean I can't tear it down and build a shopping mall or parking lot on the property? But that's the American way.
Theme park because there's no way I'm staying in a most likely to be haunted castle.
A theme park. There are a lot of restored castles to see.
