Would it be possible, in the 18th century, to set up a sort of foundation to care for a house for a specified period of time before it could be sold to someone else. I'm talking a period of several hundred years. Money could be made to not be an issue.
Basically this is the scenario.
Person A wants to be able to will the house to Person B, but B won't be alive for another two hundred or so years to take control of the house. A wants to put in his will that the house will be maintained (possibly used as an art museum or some such thing) until the 21st century, at which time it will revert to private ownership and be sold for x amount. B will be aware at what point the house will go on the market, and therefore be able to purchase the house for a relatively low purchase price.
It's convoluted but would be extremely helpful for the Nanoing.
EDIT: Question answered in a variety of interesting ways. Explaining the process (whatever I choose) will certainly boost the old word count. Thanks for all the help!
EDIT 2: I don't know why my subject line didn't post the first time. I'm really sorry, and have no excuse except for maybe quirky computer.
