Don't forget to factor in maintenance costs. If you own the place, you're on the hook for maintenance, which can be pretty high for old buildings. While the asset may appreciate in value over time, the cost of carry may negate that price appreciation.

Or you can decide not to do maintenance but then the value won't appreciate.

I guess it's a nice place and people want to have events at nice places and if they held it for 200 years it would be a good investment?
