What is the story behind the Castle of Muskogee http://www.thecastle.org/index.html ? Was this built from the ruins of a real medieval castle brought over to Oklahoma for a home by some 1920’s oil baron or was it strictly made for a tourist attraction? If it was built from the ruins of a real castle then where is this castle from, what was it’s name, and what is it’s real history?
Welcome, to the SDMB, jdhall.
I don’t know the answer to your question, but: If you will carefully read the forum descriptions, you’ll see that this question more properly belongs in the GQ (General Questions) forum. Cafe Society is for the various arts.
You will get questions answered much more quickly by posting them in the proper forum.
Perhaps a moderator will move this for you, and in GQ you will find teeming millions**[sup]TM**[/sup] waiting to provide instant answers. 
It is strictly a tourist attraction thing. This is easily verified just by looking at the interior pictures, but I have been in thing (SCA group in Stillwater used it for an event) and the pictures flatter it.
Improvements have been made on it since I was there but it still looks best from the outside. At a distance.
