See how many scenes you can find in this under two minute video clip that contains images from both Singer Castle and Boldt Castle. Both castles are represented many times. (Hint: See a great clip of Singer Castle at 1:24.) The more I looked, the more I found! There are also scenes from many other surrounding sites.
