Top 5 Biggest/Largest Castles in the World

So where is the biggest or largest castle in the world located? Is it in Europe? Or is the largest castle in North America? How would you know the total area of a castle? An article came up with an idea to compute the size using KML Area Calculator. The top 5 on the list are shown below. I added photos of the castles.
