Ok, it's not actually a castle, but it reminds me of one! The building is actually none other then the, James P. Davis Hall, that is located on Wyandotte County Lake in Kansas City, Kansas. Nestled in a hillside, if you didn't know this place was there you wouldn't be able to find it. It's rented out for many things, Weddings being the most common! It's very romantic, secluded, charming, and breath taking! Rachel loved posing next to it!! Some of the shots took on a Gothic look, which only added to my tagging it a Castle! 
Enjoy!
