You won't be able to see anything from the public areas of the street. To see the castle you must take the tour.
You meet at the bakery in Bellville and then all go together to the castle. You have to go thru a locked gate. Don't know if they relock or not. Then we walked around the castle, then went into the castle. We were also allowed in his living area too. We had lunch at his table. Had a great time. Try not to go in the heat. There was ac in his living quarters but too many people made it hot.
I don't think you can. It's a Castle but it's his home so you can not go inside the Castle. You might be able to walk around the property. Stop in at the Bakery and ask.
