3. Congdon Castle, Yakima

Wonder if secret treasures lie around here somewhere? How about a secret castle in Washington? As grand as it is to look at, this 30,000-square foot stone castle is occupied by a family, so it's not currently open to the public. While privacy is understandable, you can't help but wonder how amazing it looks on the inside too. It has been noted that the castle features 80 rooms, 18 of which are bedrooms, a lookout tower with a sleeping porch, and even an indoor swimming pool. If you do happen to come across this royal fort near Yakima, you can always admire the exterior!
