The suggested donation is $10, but you can give as much or as little as you like.
Check the official website.
When my son and I visited, I donated $10 for each of us. I did see others donate less or nothing at all. But it is a beautiful piece of architecture that has no source of income, and I believe most of the employees are on a voluntary basis, which justified it for me.
It is technically free. But they appreciate donations. It's a great place to visit, I highly recommend it.
It's actually free and they just ask for a kind donation on your part ... go enjoy yourself
The tour is free, however you can donate something to help maintain the property. $5 a person is a good rule of thumb. Enjoy this unique home.
