It is a privately owned residence and I dug up a little bit about it on the internet.

If you want to know more about my trek around the country the main page for that is here: Seeing Medieval America

I did find something that said the owner is very receptive to people wanting to visit and check out the castle. But, I didn't feel comfortable about that. It is on a private road with signs so I just did a drive by and stopped and took a picture. That's about it. It is a mysterious little castle on a peninsula in Florida.

Here is a short video of me driving by this castle.
